Magnetic dipoles & dipole moment | Moving charges & magnetism | Physics | Khan Academy
A tiny current loop act's as a tiny magnet technically called a magnetic dipole. The strength of that tiny magnet, the magnetic dipole moment m, is given by m = NIA, giving the units - Ampere meter square. The magnetic dipole moment is a vector quantity and its direction is given by the right-hand thumb rule. Magnetic dipoles are different than ...
