Two short magnets AB and CD are in the X-Y plane and are parallel to X-axis and coordinates of their centres respectively are and . Line joining the north-south poles of CD is opposite to that of AB and lies along the positive X-axis. The resultant field induction due to AB and CD at a point P(2,2) is . When the poles of the magnet CD are reversed, the resultant field induction is . The value of magnetic moments of AB and CD (in A m) are:
