GEOLOGY

Detailed explanation-1: -Magnetic materials are those which are attracted to a magnet. Examples of such materials include iron, nickel, and cobalt, etc.

Detailed explanation-2: -Magnets attract iron due to the influence of their magnetic field upon the iron. When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well. This, in turn, creates an attraction between the two magnetized objects.

Detailed explanation-3: -A magnet is an object that attracts iron objects.

Detailed explanation-4: -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-5: -Iron is magnetic in its form. The form occurs below a special temperature called the Curie point, which is 770 °C. Iron is paramagnetic above this temperature and only weakly attracted to a magnetic field. Magnetic materials consist of atoms with partially-filled electron shells.
