What is the magnetic moment of an electron orbiting in a circular orbit of radius r with a speed v?

Explanation

To find the magnetic moment of an electron orbiting in a circular orbit of radius \( r \) with a speed \( v \), we can follow these steps:

### Step 1: Understand the Concept of Magnetic Moment
The magnetic moment \( \mu \) of a current loop is given by the formula:
\[ \mu = I \cdot A \]
where \( I \) is the current flowing through the loop and \( A \) is the area of the loop.
