current loop behaves like a magnetic dipole. The magnitude of the magnetic moment‚ associated with a current loop‚ equals the product of the area of the loop and the current flowing through it. Its direction is normal to the plane of the loop and is along the direction of advancement of a right handed screw rotated in the sense of current flow in the loop. It follows that for a current loop of area A‚ carrying an anticlockwise current of magnitude I‚ the equivalent magnetic moment is
