Answer 1

Answer;

A substance that is magnetic is a substance that can generate or produce magnetic field

Explanation;

• Magnetic substances generate magnetic field since they have atoms or molecules that have unpaired electrons.
• Magnetic materials may be either paramagnetic or ferromagnetic. Paramagnetic materials are materials such as aluminium in which become magnetized in a magnetic field but their magnetism disappears upon the removal of magnetic field.
• Ferromagnetic materials are materials such as nickel and iron which can reatin their magnetic properties even when magnetic field is removed.
