a deflection magnetometer is adjusted in the usual way.when a magnetometer is introduced,the deflection observed is @(theta),and the period of oscillation of the needle in the mangetometer is T.when the magnet is removed the period of oscillations is T0.the relation between Tand T0 is A)T^2=T0^2 Cos @
