Current Loop as a Dipole

A current carrying coil behaves like a magnetic dipole having north and south poles. One face of the loop behaves as north pole while the other behaves as south pole.

A current loop behaves as a magnetic dipole with magnetic moment M.


Like the poles of a magnetic dipole, the two faces of a current loop are inseparable. A magnetic dipole in a uniform magnetic field behaves the same way as an electric dipole in a uniform electric field. A magnetic dipole also has a magnetic field around it similar to the electric field around an electric dipole.
