The work done in turning a magnet of magnetic moment 'M' by an angle of `90^(@)` from the meridian is 'n' times the corresponding work done to turn it through an angle of `60^(@)`, where 'n' is given by

Explanation

To solve the problem of finding the value of \( n \) in the context of the work done in turning a magnet, we can follow these steps:

### Step 1: Understand the Work Done Formula
The work done \( W \) in rotating a magnet in a magnetic field is given by the formula:
\[ W = MB(\cos \theta_1 - \cos \theta_2) \]
where:
