Dipole

In physics, a dipole (from Ancient Greek (dís)'twice' and (pólos)'axis') 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).A magnetic dipole represents a sufficiently small magnet such as those due to atoms, molecules, and electrons.The strength of a dipole, whether electric or magnetic, is characterized by its dipole moment, a vector quantity.
