In the equation M = Pm x B, the value Pm means the dipole magnetic moment, M is the torque acting on the current-carrying circuit, B is the external magnetic field. The equation shows that moment M = 0 if the angle between the normal to the contour and the magnetic field is 0 or 180°. Set the nature of the equilibrium position of the current-carrying circuit (stable, unstable or indifferent) for both angle values.
