Salt Spray and Neodymium Magnets

Corroded neodymium magnet sphere

When designing a permanent magnet for a given application, myriad factors must be considered, including material, grade, size, shape, total mass, direction of magnetization, and other aspects.  However, the designer must also take into account environmental considerations and consider exposure to strong electromagnetic fields, wild swings in operating and maximum temperature, and, for purposes of…

X-ray and Gamma Ray Radiation Effects on Neodymium Magnets

Bunting provides sintered Neodymium-Iron-Boron (NdFeB) magnets across a wide range of applications due to their excellent magnetic properties.  These high energy magnets are often employed in devices such as medical mixers and stirrers, where their strong magnetic fields are crucial for efficient operation. However, these devices require sterilisation through both X-ray and Gamma-ray radiation.  In…

What is a Neodymium Magnet?

Neodymium Iron Boron Rare Earth Magnets are used everywhere and are among the strongest permanent magnets.  But what exactly are they? The Neodymium Iron Boron Magnet (Neo, Neodymium, NdFeB, NIB, or Neomagnet) is the most widely used type of permanent rare earth magnet.  The high-strength permanent magnet is made from an alloy of neodymium, iron and boron…
