State any rule which relates the direction of electric current and the direction of the accompanying mangnetic field due to circular coil carrying current.

Explanation

To answer the question regarding the relationship between the direction of electric current and the direction of the accompanying magnetic field in a circular coil carrying current, we can refer to the "Right-Hand Rule" or the "Clock Face Rule". Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding the Setup**:
- Consider a circular coil through which electric current is flowing. The direction of the current can either be clockwise or anticlockwise when viewed from a certain point.

2. **Applying the Right-Hand Rule**:
...
