How can you make a permanent magnet
WebAnswer (1 of 12): Choose a material that is ferromagnetic (magnetic by the same mechanism as iron - the strongest type) and has a large magnetic "coercivity" (a measure of the strength of external field required to change the material's magnetism - so it will keep its magnetism when you're done)....
