Write the equation of the periodic time for an oscillating bar magnet in a uniform magnetic field.

(N/A) The periodic time $T$ of a bar magnet oscillating in a uniform magnetic field $B$ is given by the formula:
$T = 2 \pi \sqrt{\frac{I}{mB}}$
Where:
$T$ is the time period of oscillation.
$I$ is the moment of inertia of the bar magnet.
$m$ is the magnetic dipole moment of the magnet.
$B$ is the strength of the uniform magnetic field.
