Question

Define magnetic dipole moment of a current loop

Open in App

Solution

The magnetic moment m of a current loop is the vector whose magnitude is equal to the area of the loop times the magnitude of the current flowing in it (m = IA) and whose direction is perpendicular to the plane in which the current flows.
