Are All Metals Ferromagnetic?

The original question was probably meant to be "Why are all metals ferromagnetic?" The answer is that most metals are not ferromagnetic. In terms of objects readily found in a house, the ones that stick to a permanent magnet do so because they probably contain iron, nickel, or cobalt.

Which metal is not ferromagnetism?

Stainless Steel

Ferritic and martensitic stainless steels are magnetic due to their iron composition and molecular structure. Austenitic steels, on the other hand, do not display ferromagnetic properties because of a different molecular structure.
