REE Recovery from End-of-Life NdFeB Permanent Magnet

The size of the magnets ranges from less than 1 g in small consumer electronics to about 1 kg in electric vehicles (EVs) and hybrid and electric vehicles (HEVs), and can be as large as 10002000 kg in the generators of modern wind turbines. NdFeB permanent magnets contain about 3132 wt% of rare-earth elements (REEs).

Things to Do With Rare Earth Magnets Sciencing

Apr 24, 2017Neodymium iron boron (NIB) magnets are usually called neodymium or rare-earth magnets. They are extremely strong, having a magnetic pull-force that is 10 times greater than ferrite magnets and 20,000 times greater than the Earth's magnetic field. These magnets are brittle as well as powerful and they can shatter easily.
