Should rare earth metals continue to be used in magnets? How come?

No because since they are rare they should find some other metal for this because they're rare so we are going to run out soon because we are using them for magnets.

P. S. if you can think of any thing else to put on go a headand do it because your answer could be yes for some reason

I believe yes because then if some how someone discovers a new metal substance then we can judge wheather or not that substance is magnetic.
