Like charges repel each other, and opposite charges attract each other. The electric force is a non-contact force that does not require objects be touching in order to act. Instead, the electric force acts through an electric field. The strength of the electric forces two objects exert on each other depends on the charges of both objects, as well as the distance between them.

All magnets, no matter how small, have both a north and south pole. Like poles repel each other, and opposite poles attract each other. The magnetic force is a non-contact force that does not require objects be touching in order to act. Instead, the magnetic force acts through a magnetic field. The strength of the magnetic forces two objects exert on each other depends on the strengths of the magnets, their orientations, and the distance between them.
