In a deflection magnetometer which is adjusted in the usual way. When a magnet is introduced, the deflection observed is theta and the period of oscillation of the needle in the magnetometer is T . When the magnet is removed, the period of oscillation is T_(0) . The relation between T and T_(0) is

A deflection magnetometer is adjusted and a magnet of magnetic moment M is placed on it in the usual manner and the observed deflection is theta. The period of oscillation of the needle before setting of the deflection is T. When the magnet is removed, the period of oscillation of the needle is T_(0) before setting to 0^(@). If the eart's induced magnetic field is B_(H) , the relation between T and T_(0) is
