Rare Earth Magnets in Electric Vehicle Motors
The global move towards the electrification of vehicles continues to gather momentum. In 2010, the number of electric cars on the world’s roads reached 7.2 million, of which 46% were in China (iea.org/reports/global-ev-outlook-2020). By 2030, the number of electric cars is expected to swell to 250 million, a massive growth in a relatively short time.…

On January 1st, nobody could have predicted the challenges businesses would face in 2020. Despite the restrictions and obstacles presented by the Covid-19 pandemic, companies adapted and continued to design and manufacture as they supported customers. December provides the ideal opportunity to reflect on many of Bunting-Berkhamsted’s positive news stories shared in 2020. A Positive…
Read MoreExplaining Neodymium Magnet Strength
Neodymium Rare Earth Magnets are the strongest commercially available permanent magnets in the world. Originally invented by General Motors and Sumitomo Special Metals in the early 1980s, Neodymium Magnets are a key component in mobile phones, computers, wind turbines, and modern cars. The list of applications is nearly endless. As the name suggests, the prime…
Read MoreMagnet Comparison: Neodymium and Samarium Cobalt Rare Earth Magnets
Neodymium Iron Boron NdFeB (i.e. Neodymium) and Samarium Cobalt SmCo are both ultra-strong rare-earth permanent magnets. Both are brittle in nature and subject to catastrophic damage if subject to severe impact (i.e. dropping). However, that is where the similarity ends and, when selecting a magnet material for a specific application, our design engineers assess each…

Neodymium Iron Boron Rare Earth are the strongest permanent magnets presently available. They are a hidden key component of mobile phones, cars, and computers. When speaking to customers, we identified a number of frequently asked questions, which we will attempt to answer in this latest blog. Technical product information: Neodymium Magnets What are Rare Earth…
Read MoreSensor Magnets
Sensors are used everywhere from vehicle engine management systems to Smartphones determining if the flip cover accessory is closed. Modern everyday life would be very different without sensors and the operation of many of these sensors rely on magnetism. As products evolve, so have the range and specification of sensor magnets. A magnetic sensor converts…
Read MoreReplicating True Radial Arc and Ring Magnets with Pseudo-Radial Arcs and Rings
The manufacture of anisotropic radially magnetised arcs and rings is significantly different to the production of diametrically magnetised rings and arcs. Radially aligned and magnetised anisotropic arcs and rings are only possible in fully dense sintered NdFeB and need a dedicated press tool and magnetising fixture and have a limited physical envelope (Max OD 85mm).…
Read MoreSurface Mounted Arc Magnets
Bunting is capable of supplying almost any shape and size of a permanent magnet, but one of the most popular shapes is the arc. Arc magnets are used in a wide range of magnet assemblies, but in particular, surface mounted electric machines. There are four main types of arc magnets and these are: Each arc-type…
Read MoreBespoke Pot Magnet Design for Oil and Gas Application
An international Oil and Gas company turned to Bunting when investigating designs for a novel magnetic system to act as a pressure relief valve. The Pot Magnet assembly design requirements were complex with a number of significant technical challenges. The initial design evaluation identified that the bespoke magnet assembly would be based on a simple…
