A mass, a charge and a magnetic material will interact with gravitational, electric and magnetic fields respectively.

Explanation:

For each case, the object will experience a force along field lines, either towards the direction of increasing or decreasing potential.

Gravitational forces are always attractive and point in the direction of decreasing potential. Electric and magnetic forces can be both attractive and repulsive.

Other interactions include:

  1. Charges and magnetic materials are/have masses and will interact with gravitational fields.

  2. A moving charge will experience an electric force in the presence of an external magnetic field. (The current and the B field should not be parallel though.)
