Hello folks,
There was a recent discussion on the radio about rare earth materials -- they are not rare, actually; but the concern is that 95%+ of the production is in China. Apparently the most uncommon of these so-called rare earth materials are about 10X more common than gold; so their name is a misnomer. Here's a link to the radio show:

My question is: can the permanent magnets used in EV motors be reused (by "zapping" them to strengthen them which I know can work with ceramic magnets), and/or can they be recycled at the end of their useful life? Do you think that rare earth magnets are required to get the best efficiency, or can AC motors be virtually as efficient; and avoid the need for any permanent magnets?
Sincerely, Neil
