Dear Pratik,

 The time period of vibrating T = where is the moment of inertia of the bar magnet about the axis of oscillation.
m = mass of the magnet
l = length of the magnet
b = breadth of the magnet
BH= horizontal component of earth's magnetic field


  here,  M' = M - M = 0 as opposite poles on same side

as T is inversly proportional to M so,  T = ∞
