An electric current flows in a horizontal wire from East to West. What will be the direction of magnetic field due to current at a point (i) North of wire, (ii) above the wire.

Explanation

To determine the direction of the magnetic field due to a current flowing in a horizontal wire from East to West, we can use the right-hand rule. Here’s how to solve the problem step by step:

### Step-by-Step Solution:

1. **Identify the Direction of Current**:
- The current flows from East to West in the wire.

2. **Determine the Magnetic Field Direction at a Point North of the Wire**:
