High Strength Magnets – 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.
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
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.
