Answer 1

Answer:

Magnets are rocks or metals that create an invisible field around themselves. ... The presence of a magnetic field is why you can cover a metal refrigerator door with magnets. A magnetic field is concentrated around the ends of magnets. These ends are called poles. All magnets have two poles: a north pole and a south pole.
