Consider a free bar magnet oscillating in uniform
\( \mathrm{P} \)
magnetic field. Which of the following is correct about time period (T)
(1) \( T \propto \) length of bar magnet
(2) \( T \propto \frac{1}{\sqrt{\text { polestrength }}} \)
(3) \( T \propto \frac{1}{\sqrt{\text { Magnetic flux density }}} \)
(4) \( T \propto \sqrt{\text { length of bar magnet }} \)
