A circular loop of radius R carries a current I. Another circular loop of radius r(ltltR) carries a current I. The plane of the smaller loop makes an angle of 30^@ with that of the larger loop. The planes of the two circles are at right angle to each other. Find the torque acting on the smaller loop.
