4)magnets attract or repel other magnets.

 I think the answer is 4)Magnets attract or repel other magnets.

Answer;

4) Magnets attract or repel other magnets.

Explanation;Magnets are materials that have the capability of generating magnetic fields. They repel non-magnetic materials such as wood, plastic etc. and attract magnetic material such as iron and steel.Magnets may attract or repel each other based on the basic law of magnetism which states that like poles repel and unlike poles attract. Therefore, when two north poles of different magnets are brought together they repel, while north pole will attract south pole of another magnet.
