Buy Made To Order online with e-Magnets UK™

e-Magnets UK stocks a wide range of magnets and magnetic assemblies available for Next Working Day delivery. However, you may have a need for a magnet that we do not show on our web site.

If you cannot find the right shape or grade of magnet or magnetic assembly, please contact us. We offer an extensive manufactured-to-order service for all types of magnets including Neodymium Iron Boron (NdFeB), Samarium Cobalt (SmCo), Ferrite, Alnico, Bonded, Injection Molded, Compression Molded, Rubber and Magnetic Assemblies (Pot Magnets, Magnetic Sweepers, Magnetic Rods and Grids, etc). If you need a custom made magnet (also known as bespoke magnet, made to measure magnet, made to order magnet, special magnet, non-stock item magnet, etc), we can help you.

Simply supply a drawing or sketch of your requirements for a free and without obligation quotation.

If you are not sure what you need then please feel free to call us on 0114 276 2264 and ask for a member of our technical sales team or alternatively send an e-mail to sales@e-magnetsuk.com

The photograph shows a high specification custom Neodymium Iron Boron (NdFeB) magnet destined for a new customer who asked us to make a magnet to their design requirements as part of our special Made To Order service.


We manufacture the complete range of magnetic grades for each permanent magnet material type. We also offer a range of coating finishes for the magnets. The below information is a summary of the Permanent Magnet Material Technical Data Sheets that we supply to our customers. We can send to the complete Permanent Magnet Data Sheets (including magnetic performance specifications, temperature coefficients, maximum operating temperatures, physical properties, example BH curve, etc) for each magnet material upon request.


Neodymium Iron Boron / NdFeB magnetic properties (minimum values shown; please ask us for full data sheets to explain the grades in more detail):-
