Consumption of rare earth magnets in transportation is estimated to rise from 7,000 tons in 2015 to 17,000 tons in 2020. Government mandates to reduce pollution, as well as high gasoline prices, are driving users to purchase more environmentally friendly vehicles. Permanent magnet machines are currently the leading choice for high performance automotive applications. The rotor’s well-balanced magnetic field and the lower stator current requirement, paired with very strong positional control, result in a higher motor efficiency. Two common choices for electric vehicle applications are [neodymium magnets](http://www.arnoldmagnetics.com/en-us/Products/Neodymium-Magnets) and [samarium cobalt magnets](http://www.arnoldmagnetics.com/en-us/Products/RECOMA-SmCo-Magnets-en), and each has its advantages.
