Question : 28

Total: 160

Two short magnets AB and CD are in the X−Y plane and are parallel to X-axis and co-ordinates of their centres respectively are (0,2) and (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 100×10−7T. When the poles of the magnet CD are reversed, the resultant field induction is 50×10−7T. The value of magnetic moments of AB and CD (in Am2 ) are :

300;200
600;400
200;100
300;150
