Magnets Attract Crowds at Cenex LCV

High Interest In The Latest Magnet Technology

A significant increase in visitors to the Bunting Magnetics stand at Cenex-LCV 2018 [compared with 2017] reflected the high level of interest in new magnet technology.  In addition, the growing importance of low carbon vehicles was highlighted with a record number of attendees and exhibitors at the show.

By 2021, phased in from 2020, the fleet average emissions in the European Union for all new cars will be 95 grams of CO2 per kilometer.  This equates to a fuel consumption of 4.1 litres/100 km for petrol engines and 3.6 litres/100 km for diesels.  Earlier this year, it was reported [The Guardian] that CO2 emission from the average new car sold rose for the first time since 2000, reaching an average of 121.0 grams per CO2 per kilometer (the same as in 2015).

The Slow Move To Electric Vehicles

Sales of electric cars continue to disappoint, with many drivers reluctant to purchase due to the limited range before charging is required.  However, there are major changes happening in the industry and even luxury car producers such as Aston Martin (RapidE) and Jaguar (I-Pace) released or under development.

The key to the success of the electric car is the efficiency of energy conversion, with enhanced battery life and improved motor performance.

The Importance of Magnets in Electric Cars

The necessity of improving motor performance was one of the primary reasons for Bunting’s attendance at the event.  Bunting continues to develop new Neodymium Rare Earth Magnet technology that enables magnets to operate at higher temperatures for longer periods of time.

Many of the discussions on the Bunting stand focused on the new Grain Boundary Diffused Neodymium Magnets, with over half our visitors requesting further information after the show.  These new Magnets offer higher performance from the same space envelope and allow designers to consider solid magnets rather than laminated magnets as a more cost effective solution for the first time in a decade.

Visitors to the stand also showed a great deal of interest in bespoke magnetising systems that can post assembly magnetise rotors with embedded magnets, and surface mounted multipole or Halbach arrays.  Meetings have already been confirmed for two magnetiser projects.

Magnets at Cenex LCV 2018 Event

Bunting Exhibit High Strength Magnets at Low Carbon Vehicle Event

The most advanced high strength magnet technology will be on show on the Bunting Magnetics stand C1-14 at the Cenex-LCV 2018 event (Millbrook, Bedfordshire, UK, 12th and 13th September 2018).  Cenex-LCV is the UK’s premier low carbon vehicle event.  There is an exhibition area as well as an extensive seminar programme.

Presently in the UK, there are approximately 26 million registered cars of which 37,500 are alternatively fuelled (i.e. they do not run on petrol or diesel).  For many car owners, the decision on whether to purchase an electric car is dependent on their mileage.  Improvements in battery technology continue to extend the distances electric cars can travel with Nissan announcing a 168 mile range for the latest Leaf electric car.  Even Jaguar has announced plans to develop the E-type Zero sports car.

Magnets and Electric Cars

Magnets are present in any item that uses a motor or electricity to function.  Electric cars included.  One of the primary components in any electric motor is the magnet.  Inside the motor is a spinning wire coil that is surrounded by strong permanent magnets, commonly Neodymium Rare Earth.  When an electric current is induced in the coil, it emits a magnetic field, opposing the magnetic field emitted by the strong magnets.

Electric Car Fun Photo

When the same pole of a magnet is pushed together, they repel.  The same principal is used inside an electric motor.  In this case, the repulsion caused by the opposing magnetic field causes the coil to spin at a high speed.  The coil is attached to an axle that drives movement in the wheels.

The continued rise in popularity of electric cars and wind turbines for wind energy is considered to be one of the reasons for a rise in the price of Rare Earth minerals.

Developments in Magnet Technology

Dislocation Grain Boundary Aleration

At the Cenex-LCV 2018 event, Bunting will be showing new developments in permanent magnet technology.  The latest permanent Magnet can now maintain their magnetic properties at higher temperatures.  The development of these new Neodymium Rare Earth Magnets is based upon Grain Boundary Diffusion technology and maximising the advantages of adding Dysprosium into the magnet mix.

Grain Boundary Diffusion Technology

Pushing NdFeB Magnets Hotter, Harder and Faster

Neodymium (NdeFeB) Rare Earth Magnets are used throughout industry and, as demand increases from the Energy, Automotive, Aerospace and Down Hole markets, the drive is towards producing magnets that have the highest magnetic energy under the harshest of conditions such as:

These are typical applications where the Samarium Cobalt (SmCo) Rare Earth Magnet has been traditionally preferred to NdFeB, but with the rise in cost of Cobalt and the current high price of Dysprosium (Dy), there has been a growing demand for a better performing NdFeB.

A Typical Example

The temperature of a permanent magnet in a motor could rise above 150 deg C under maximum load conditions, which would cause a magnet with lower intrinsic coercivity to become de-magnetised.  To satisfy the higher temperature requirement, the intrinsic coercivity of magnet could be increased by adding the heavy rare earth element Dysprosium.

With added Dysprosium, the magnet will suffer less loss in the same temperature condition, but will be more expensive and have a lower residual magnetic induction or magnetic remanence, otherwise known as Br and BHmax (if the original grade was greater than 35MGOe).

Grain Boundary Diffusion (GBD) Technology

Rather than add expensive Dysprosium to the total mix and waste it in the middle of a grain, new technology allows the Dysprosium to diffuse from the surface around all of the the grain boundaries.  In Grain Boundary Diffusion (GBD) technology, when the heat treatment temperature is higher than the melting point of Nd-rich phase, then the Dysprosium/Terbium compound on the magnet’s surface can penetrate into the magnet through its grain boundary.

GBD

The image on the left shows the light blue as Dysprosium and the dark blue as NdFeB.  With Grain Boundary Diffusion the Dysprosium in the right picture is only at the grain boundaries, where it is needed.

By reducing the Dysprosium in the grain and ensuring it is only at the boundary the Br and BHmax remain unchanged and less Dysprosium is used in the production process, reducing the manufacturing cost.

This new technology is being used by Bunting Magnetics in the UK to produce a range of grades of higher performing NbFeB Rare Earth Magnets, which are listed in the table below.  The grade is proportional the magnet shape and size.

Offices Would No Longer Function Without Magnets

The Vital Role of the Simple Magnet

Stating that an office would not be able to function without the presence of magnets is pretty bold.  Immediately you are thinking that there are other ways to pin notices to white boards or neatly store paperclips.  Important, maybe, but these are not critical to our daily life in work.

So, if magnets were removed from the workplace, what would be the effect?

There Would Be No Computers

F33A9377

Ironically, the reason for there being paranoia about putting a computer near to a magnet is that the hard drive uses disks of magnet material to store data.   An electromagnet, positioned in the read/write head, writes data to the disk by magnetising small sections (called sectors) in a direction to indicate a 1 or 0.  The magnets used are high strength Neodymium Rare Earth, the most powerful permanent magnet presently available.  Without the magnet, it would not be possible to store all that data.  Presently, there is a great deal of research taking place to recover and recycle the magnet material from computers.

There Would Be No Electronically Generated Sound

Without magnets, the office might be a little quieter as it would not be possible to listen to the latest England Test cricket match or music on Radio 1.  Inside every speaker in a screen or radio there is a wire coil and magnet that converts electronic signals into sound vibrations.  Also, as a mobile phone and landline telephone relies on a speaker for communication, these would not exist without the presence of magnets.

Maybe not having a mobile phone would be a good thing…

There Would Be Less Environmentally Friendly Power

Wind_Turbines_SunSet

In 2017, wind generated power contributed 15% to the total UK electricity generation, a percentage that is expected to increase in 2018.  Modern wind turbines use permanent magnet generator (PMG) systems instead of gearboxes.  The Neodymium or Samarium Cobalt Rare Earth Magnets replace traditional electromagnetic coils to produce the necessary magnetic field for magnetic induction and the generation of electricity.

So, without magnets there would be no computers, no radios, no mobile phones and less energy.  Also there would be no magnets for the office notice board and desks strewn with paperclips.  Maybe we need to be thankful for the existence of the simple magnet!

Health and Safety Attracts Tidi-Cable to Bunting

Innovative Magnetic Cable Safety Device

Bunting Magnetics has supplied bespoke Ferrite Magnets to Tidi-Cable for their newly released Tidi-Patch ® Magnetic.  Tidi-Patches instantly lift dangerous trailing cables off the ground and remove potential trip hazards.  They are used on construction sites, at festivals/events, in factories, in film studios, in mining operations, on oil/gas production sites, shipping yards, and railways.

Tidi Patch Magnetic-

Tidi-Cable Ltd is the leading manufacturer and distributor of heavy-duty cable management products in the UK.  Their products are all designed to raise 110v trailing leads off the floor, eliminating any potential trip hazard.

Bunting supplied shallow Ferrite Pot Magnets that were then connected to the back of the new Tidi-Patch ® Magnetic.  Using a Magnet to hold the Tidi-Cable in place eliminates the need for drilling.  This means that there is no silica dust, no noise pollution, and a reduced risk of hand-on-vibration syndrome.  It also leaves no mess or residue behind.

The Tidi-Patch ® Magnetic is designed to hold up to 6 x 110v arctic cables and has a maximum load capacity of 2kg.

“Using Magnets to hold and secure the Tidi-Cable is a clever idea,” explained David Hills, Bunting’s Head of Sales.  “However, it was important for us to fully understand the application before making a recommendation.  The magnet needed to have enough magnetic force to safely secure onto a metal beam and hold up to 2kg of cable.  Our engineers selected a shallow but strong Ferrite Pot Magnet, which provides ample holding force whilst not making the Tidi-Cable cumbersome and heavy.  The Tidi-Patch ® Magnetic is a very clever product.”

Following very positive feedback after UK site trials, this innovative product is now available to purchase.

Ever Increasing Rare Earth Metals Demand

Cutting Edge Technology Could Drive Up Rare Earth Magnet Prices

The global market for rare earth metals will be worth an estimated US$ 7362 million by 2026, according to Future Market Insights.  This projection equates to a compound annual growth of 8.5%.  The growth in demand is expected to put pressure on prices.

The vast majority of Rare Earths are mined in China, where there are 36% of the world’s estimated reserves.  Changes in pricing can be political, as can restrictions on mining and exports.  As well as being the leader producer, China is also the leading consumer of Rare Earths.

Rare_Earth_Metal_Market

The Rare Earth suite of elements includes Neodymium, Lanthanum, Cerium, Praseodymium, Gadolinium, Yttrium, Terbium, and Europium.  Neodymium has been used used in the manufacture of high strength magnets since 1982.  With technological developments, Neodymium Magnets have got stronger.

Neodymium Applications

The demand for Neodymium continues to grow at a high rate.  In 2016, Neodymium accounted for 38% of sales of all Rare Earths and this is not expected to change.  Neodymium is used to make powerful Rare Earth Magnets that are used in loudspeakers and computer hard drives.  Neodymium Magnets are also used in green technologies such as the manufacture of wind turbines.

Electric Car

Neodymium also is one of several Rare Earth Elements (along with lanthanum, cerium and praseodymium) used as the intermetallic compound that forms the negative electrode in a NiMH battery used increasingly in hybrid and electric vehicles.

Future Demands

Once charged, high strength Neodymium Magnets do not need any power.  Subsequently, many product designers are aiming to harness this ‘free energy’.  Also, the global move towards electric transportation, where Rare Earths play a vital role in battery development, is expected to drive up the demand.

2017 Review of Magnet News and Blogs

News and Technical Articles on Magnets and Magnetic Assemblies in 2017

2017 has been our first full year of posting news and technical articles.  As we approach the end of 2017, we thought that it would be interesting to look back on a busy and exciting year!

January

Our first blog of the year looked at the simple Magnetic Sweeper, used in factories, warehouses and in car parks to remove metal from floors.

This was followed by an article on Car roof top magnets, that are seen on the top taxis across the UK.

Also in the month, we published an article on a complex Rare Earth Magnet assembly designed to act as an emergency brake on an offshore winch.  The Bunting magnet designs team had worked closley with the client to develop and manufacture a unique high strength magnetic assembly.

February

Matthew Swallow, our Technical Sales Engineer for Magnets and Magnetic Assemblies, reported back from the UK Magnetic Society’s even on Non-Rotating Machines.  This included a fascinating review of how the US military intend to catapult planes from war ships in the future.

March

Bunting Magnetics Magic Magnetic Coins

Our product range of the month was Work Holding Magnets, used extensively across the manufacturing sector to secure, hold and lift metal components and parts.

We also looked at Magnet Magic and asked how these 4 coins were balanced on the edge of a mug.  This trick used the power of a magnetic block.

April

We reviewed the manufacture of specialist Magnetic Assemblies at our facility in the UK.  Many of the designs are bespoke and we examined the science behind a high performance magnetic coupling.

May

In May we explained where the name ‘Rare Earth’ originated when talking about high strength magnets.  Although commonly believed to be a relatively recently developed material, the original work dates back to the 1960s.

June

One of our most popular articles in 2017 provided health and safety advice for people handling and using high and low strength magnets.

Then we talked about the importance of the simple compass in the development of the world we know today.  The compass is believed to be over 2000 years old and helped many of our famous explorers discover new worlds.

July

Denis Elkins, our Quality Assurance Manager, announced our successful transition to the ISO9001:2015 Quality and ISO14001:2015 Environment Standards.

Denis_Elkins_Bunting_Magnetics_Europe-2176

August

Reports from China highlighted concerns about the rising price of Rare Earth Magnets.  The price was being driven up by a number of factors including the rise in demand for electric vehicles.

September

We launched a new Neodymium Magnet designed specially for use in sensors at the Sensors & Instrumentation Show at the NEC in Birmingham.

October/November

We are really keen to promote engineering to young people and were thrilled to be able to show the 1st Northchurch Cub Scouts around our magnet and magnetic separator factory in Berkhamsted.  The visit ‘attracted’ a lot of attention!

Sean Connery Roger Moore

November was also our ‘James Bond’ month and we looked back at all the movies to see where 007 or the villains had used the power of the magnet.  Part 1 focused on the Sean Connery and Roger Moore years, and was followed by Part 2 and the Timothy Dalton and Pierce Brosnan era.

December

Our final news of the year was about the Christmas Magnet Competition, where Andrew McAllister from Portsmouth won 5 Magnet Science Games.  Congratulations Andrew!

Cub Scouts Attracted to Engineering by Magnets

Bunting Europe is Visited by 1st Northchurch Cubs from Berkhamsted

A Berkhamsted based Cub Scout group were recently given a tour of their local Bunting Magnetics magnet, magnetic assembly and magnetic separator manufacturing plant.  The 1st Northchurch Cubs were shown how magnets are a fundamental part of everyone’s daily life.

IMG_3966AThe visit comes at a time when industry is desperately encouraging young people to get into engineering with initiatives like Tomorrow’s Engineers Week.

“This was an ideal opportunity to introduce the exciting industry of engineering to a group of enthusiastic young people,” explained Denis Elkins, Bunting’s Quality Assurance Manager.

IMG_3957“Most people do not appreciate that we all rely on magnets every day of our lives.  Magents like Neodymium Rare Earth are a key component in mobile phones, computers, wind turbines that generate clean energy, and family cars.

“It was great to see the Cub’s faces when we demonstrated the strength of some of our magnets.  They could not believe it.  We took them onto the shop floor and showed them how we made magnets and magnetic assemblies.  The young people were fascinated.”

Bunting Goody BagsIn all 24 cubs visited the Bunting plant along with scout leaders and parents.  As well as the tour, the cubs were shown a video about magnets, given a bag full of ‘magnetic’ goodies and there was a lot of cake!

“Introducing young people to the concept of engineering and manufacturing is vitally important,” explained Denis.  “As an industry, we have a responsibility to encourage events like this, bringing young people into the manufacturing environment to see and experience first-hand the excitement of designing and building engineered components and equipment.  It was a great success and we hope to see them again in the future.”
