Gravitational forces are always attractive. Gravity is a non-contact force that does not require objects be touching in order to act. Instead, the gravitational force can be modeled as acting through a gravitational field. The strength of the gravitational forces two objects exert on each other depends on the masses of both objects, as well as the distance between their centers of mass.

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.
