GEOLOGY

Detailed explanation-1: -The metals that are magnetic (attracted to magnets) are also the metals that can be made into magnets. The most common magnetic metal is iron which is the main substance in steel. Iron is also in a mineral called loadstone which is the most magnetic naturally-occurring mineral.

Detailed explanation-2: -Ferromagnetic materials are materials that have magnetic properties similar to those of iron. They can become permanently magnetized. Examples of ferromagnetic materials are nickel, cobalt, and alnico, an aluminum-nickel-cobalt alloy.

Detailed explanation-3: -Remanent magnetization In other words, they behave in a ‘magnetic’ way. Only a few elements, including iron, can hold on to this magnetization when the magnet is removed. Such a magnetization is called a spontaneous or remanent magnetization.

Detailed explanation-4: -Iron is ferromagnetic : | Physics Questions.
