Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone.

When the current is removed, the magnetic flux often remains at some non-zero value. This is a characteristic phenomenon of ferromagnetic materials.
