Two bar magnets having same geometry with magnetic moments M and 2M, are firstly placed in such a way that their similar poles are in same side then its time period of oscillation is 
. Now the polarity of one of the magnet is reversed then time period of oscillation is 
, then

The time period of bar magnet
where 
magnetic moment of magnet
moment of inertia
and 
horizontal component of magnetic field
when same poles of magnets are placed on same side, then net magnetic moment
When opposite poles of magnets are placed on same side, then net magnetic moment 
From eqs. (i) and (ii) we observe that
