A small magnet of moment M, produces a deflection of 30º when placed at some distance from the needle of a deflection magnetometer in Tan A position.Another small magnet of double the length and thrice the pole strength is kept at same distance in Tan B position. The deflecton produced is 1) 300 2) 40° 3) 60° 4) 450
