A bar magnet is suspended in a region of earth's magnetic field such that its axis makes an angle of `60^@` with the field. Calculate the torque experienced by the magnet if its magnetic moment is `0.5 Am^2` . Assume field to be 0.4 G.

Explanation

To calculate the torque experienced by a bar magnet suspended in a magnetic field, we can follow these steps:

### Step 1: Identify the given values
- Magnetic moment (m) = 0.5 Am²
- Angle (θ) = 60°
- Magnetic field (B) = 0.4 G

### Step 2: Convert the magnetic field from Gauss to Tesla
