Neodymium Iron Boron Rare Earth Magnet
A Review of REPM 2023
Matthew Swallow, our Technical Product Manager and the Chair of the UK Magnetics Society, reports on REPM 2023, the 27th international workshop on rare earth and future permanent magnets and their applications (3-7 September, University of Birmingham, UK). REPM is a biennial academic conference held and run by a hosting university or institution with the…

Bunting has signed up as a gold sponsor of REPM 2023, the 27th international workshop on rare earth and future permanent magnets and their applications (3-7 September, University of Birmingham, UK). The biennial workshop is co-organised by SUSMAGPRO partner University of Birmingham and brings together scientists and engineers working on rare-earth permanent magnets and their…
Read MoreNon-Contact Positional Sensing
Sensor applications using magnets is not new, although the application scope continues to evolve with developments and advances in magnetic materials and magnetising technology. In this specific sensing project, the magnets are used for non-contact position sensing, which is, perhaps, one of the unique ways in which magnets are meeting the changing demands of the…
Read MoreMedical Magnet Spotlight: Magnets and Cochlear Implants
Magnets feature in a wide range of medical applications including heart pumps, surgical tools, hearing aids, and cochlear implants. A cochlear implant is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. Unlike hearing aids, which amplify sounds, cochlear implants bypass damaged areas of the ear and…
Read MoreCoatings for Neodymium Magnets
Nearly every neodymium magnet will be plated or coated and, as the most powerful permanent magnet available, they are used in many different applications. However, they possess physical characteristics that require them to be plated or coated in order to protect them from damage. In their raw form, neodymium magnets are quite brittle, and as…
Read MoreBunting Introduces Carbon Neutral Neodymium Magnets
In response to feedback from European customers, Bunting-Berkhamsted is the first magnet supplier to offer carbon-neutral sintered Neodymium Iron Boron (NdFeB) rare earth magnets sold online through the company’s Bunting-eMagnets ecommerce website. The manufacture of magnets such as NdFeB requires a considerable amount of effort and energy, from mining of the raw materials through to…
Read MoreThe History of Neodymium Magnets
The origin of the neodymium magnets dates back to 1885 when Carl Auer von Welsbach, an Austrian scientist and inventor, separated didymium into the new separate elements neodidymium (“new didymium”) and praseodidymium (“green didymium”). In time, the element names would change to neodymium and praseodymium. Neodymium (Nd) is the fourth member of the lanthanide ‘rare-earth…
Read MoreMagnets in Santa’s Workshop
Santa Claus has never been busier. Material shortages, transportation issues and inflated prices have stretched his elf workforce to the limits. His workshop is a hive of activity and, in amongst the organised chaos, magnets play an important role. So where are they? High Tech Toys use Neodymium Rare Earth Magnets Santa Claus received a…
Read MoreMagnets and the Curie Temperature
The term “Curie temperature (Tc)” or “Curie point” gets frequently mentioned when discussing magnets and magnetic properties. The Curie temperature relates to the maximum temperature a material can reach before losing its magnetic properties. On reaching a magnetic material’s Curie temperature, the spontaneous magnetisation in the material drops to zero. At this point, the material…
Read MoreNeodymium Price Trends
Updated 25th January 2024 On January 1st 2025, after rallying between August and November, the price of Neodymium fell to the lowest level since November 2020. The outlook remains uncertain, with further decreases likely in the short term. In 12 months, the price of Neodymium has fallen by 42%, way down on the peak price…
