What's the big deal. Over 40 yrs. ago right here in the U.S. I saw an electric motor with carbon fields that were(permanent magnets), compressed carbon and they were just glued to the inside of the motor case, A complete motor could be made entirely of carbon very easily. Why haven't we done so here in the U.S.?
China has not only a large supply but cheap labor and as technology followed the economics, a leading industry. The US, Australia, and Mongolia , Greenland and other places also have such metals.
Develop a motor that uses no rare earth metals Really? They can't just use iron? Iron is not rare at all, and it's probably the first thing that comes to mind when you say magnet (except Mormons, but that's another topic). And you can make permanent magnets from iron.
Carbon is lined, wireless is in, remotes are trendy, signals are well ..... , frequecies are ........ hey, gramps, dont try to hp an engine.... I am over 50 and still strong as an ox, you should be 60s
