-As you know that there are magnetic rock so the first magnet were found rather than being invented
-Permanent magnets are made from "hard" ferromagnetic materials such as alnico and ferrite that are subjected to special processing in a strong magnetic field during manufacture to align their internal microcrystalline structure, making them very hard to demagnetize.-And strong temporary magnets are made by using the principles of electro magnetism
