Not all metals are magnetic. Actually, it depends on what you mean by the word "magnetic". There are four basic types of magnetism that a material can have: superconducting, diamagnetic, paramagnetic, and lastly ferromagnetic. Superconducting materials are strongly repelled from permanent magnets. Diamagnetic materials are weakly repelled by permanent magnets. Paramagnetic materials are weakly attracted to permanent magnets. Lastly, ferromagnetic materials are strongly attracted to permanent magnets.
