Two magnets rest on a table. Because like poles of a magnet repel each other, the magnets exert a force on each other. If Magnet 1 is moved closer to Magnet 2, Magnet 2 will move. This is because– (A)objects need to touch each other in order to cause movement.

(B)magnets can only exert a force on other magnets.

(C)changing the positions of the magnets changed the energy of the system.

(D)moving Magnet 1 changed the force needed to move Magnet 2.
