The element Nickel (Ni) is one of the few ferromagnetic metals. Ferromagnetic means they are attracted to magnets and can be magnetized themselves. Most metals arenât magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium.
Ferromagnetism (including ferrimagnetism) is the strongest type: it is the only one that typically creates forces strong enough to be felt, and is responsible for the common phenomena of magnetism in magnets encountered in everyday life.erromagnetism (including ferrimagnetism) is the strongest type: it is the only one that typically creates forces strong enough to be felt, and is responsible for the common phenomena of magnetism in magnets encountered in everyday life.
