There are various kinds of magnetism, out of which ferromagnetism is the strongest type. Ferromagnetic materials are those materials that exhibit a spontaneous net magnetization at the atomic level, even in the absence of an external magnetic field.

When placed in an external magnetic field, ferromagnetic materials are strongly magnetized in the direction of the field. Ferromagnetic materials are strongly attracted to a magnet. These materials will retain their magnetization for some time even after the external magnetizing field is removed. This property is called hysteresis.

Ferromagnetism gets its name from the word ‘ferrous’ which means iron which was the first metal known to show attractive properties to magnetic fields. Ferromagnetism is a unique magnetic behaviour that is exhibited by certain materials such as iron, cobalt, alloys, etc. It is a phenomenon where these materials attain permanent magnetism or they acquire attractive powers. It is also described as a process where some of the electrically uncharged materials attract each other strongly. Ferromagnetism is a property that considers not only the chemical make-up of material but also takes into account the microstructure and the crystalline structure.

Answer:

Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. ... Only a few substances are ferromagnetic. The common ones are iron, cobalt, nickel and most of their alloys, and some compounds of rare earth metals.
