A short bar magnet placed with its axis at `30^@` with a uniform external magnetic field of `0*25T` experiences a torque of magnitude equal to `4*5xx10^-2J`. What is the magnitude of magnetic moment of the magnet?

Explanation

To solve the problem, we will use the relationship between torque (\( \tau \)), magnetic moment (\( \mu \)), and the magnetic field (\( B \)). The formula for torque experienced by a magnetic moment in a magnetic field is given by:

\[ \tau = \mu B \sin \theta \]

Where:
- \( \tau \) is the torque,
