Examine each diagram to determine what type of motion may occur. Choose the correct term for each diagram: attract, repel, no movement.

• attract

• repel

• no movement

Answer explanation

The correct choice is 'repel' because like charges or similar poles of magnets push away from each other, resulting in a repelling motion. This indicates that the objects in the diagram are experiencing a repulsive force.
