Explain with the help of a labelled diagram the distribution of magnetic field due to a current through a circular loop. Why is it that if a current carrying coil has n turns, the field produced at any point is n times as large as that produced by a single turn?

Explanation

To explain the distribution of the magnetic field due to a current through a circular loop, we can follow these steps:

### Step 1: Understanding the Circular Loop
A circular loop carrying an electric current generates a magnetic field around it. The direction of the magnetic field can be determined using the right-hand rule: if you curl the fingers of your right hand in the direction of the current, your thumb will point in the direction of the magnetic field inside the loop.

### Step 2: Drawing the Diagram
1. Draw a circle to represent the circular loop.
2. Indicate the direction of the current flowing through the loop (e.g., clockwise or counterclockwise).
