Magnetism is the property of attracting iron by a magnet.. A magnet is an object made of certain materials like iron which can create a magnetic field around it. If there are things made of iron in this field (region) they are attracted by the magnet.. What do doorbells, microwaves, and speakers all have in common? They all use . Electricity. and .
