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, like paramagnetism, occurs in materials in which atoms have permanent magnetic dipole moments. The strong interaction between neighboring atomic dipole moments keeps them aligned even when the external magnetic field is removed. Example: Iron, cobalt, nickel and number of alloys.erromagnetism, like paramagnetism, occurs in materials in which atoms have permanent magnetic dipole moments.
