A ring of mass m and radius R is given a charge q. It is then rotated about its axis with angular velocity `omega`.Find
(iii)Magnetic moment of ring.

Explanation

To find the magnetic moment of a ring of mass \( m \) and radius \( R \) that is given a charge \( q \) and rotated about its axis with angular velocity \( \omega \), we can follow these steps:

### Step 1: Understand the relationship between current and charge
The current \( I \) produced by the rotating charge can be expressed as:
\[ I = \frac{q}{T} \]
where \( T \) is the time period of one complete rotation.
