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 = ∞
