A small bar magnet of magnetic moment `9.75 xx 10^(-3) J T^(-1)` is suspended from its centre of garvity and is free to rotate in a plane containing a uniform magnetic filed. It is displaced from its stable equilibrium and the period of oscillations is found to be 2.50 s.If the moment of inertia of the magnet about its axis of rotation is `1.25 xx 10^(-5) kg m^(2)` , determine of inertia of the magnetic field.
