In physics, a dipole () is an electromagnetic phenomenon which occurs in two ways: An electric dipole formed by the separation of the positive and negative electric charges (typically in atomic and molecular systems). Electric dipoles are typically represented by a pair of charges of equal but opposite electric charges separated by a small distance. A magnetic dipole represents a sufficiently small magnet such as those due to atoms, molecules, and electrons. Magnetic dipoles are typically modeled as a loop of constant current.
