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 (0,2)(0,2) and (2,0)(2,0). 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 100×107T100 \times 10^{-7}\,\text{T}. When the poles of the magnet CD are reversed, the resultant field induction is 50×107T50 \times 10^{-7}\,\text{T}. The value of magnetic moments of AB and CD (in A m2^2) are:
