A deflection magnetometer is arranged with its arms along east-west.A small bar magnet is placed length wise with its north pole pointing east along the eastern arm with its centre 25cm away from centre of needle of the magnetometer.The needle is then found to be deflected through an angle 30degrees.if arms of magnetometer are rotated in anticlockwise through 90 degrees ,the deflection of the needle would be....
