63. If N closed loops are formed from the wire of length L , the circumference of each loop is L / N , the radius of each loop is R = L /2 π N , and the area of each loop is AR LN L N == = ππ π π 2 2 22 24 b g . (a) For maximum torque, we orient the plane of the loops parallel to the magnetic field, so the dipole moment is perpendicular (i.e., at a 90 ° angle) to the field. (b) The magnitude of the torque is then
