A closed current-carrying loop having a current I is having area A. Magnetic moment of this loop is defined as vec(mu) = vec(IA) where direction of area vector is towards the observer if current is flowing in anticlockwise direction with respect to the observer. If this loop is placed in a uniform magnetic field vec(B) , then torque acting on the loop is given by vec(tau) = vec(mu) xx vec(B) .
