The front face of a circular wire carrying current behaves like a north pole. The direction of current in this face of the circular wire is :

Options

A. clockwise
B. downwards
C. anticlockwise
D. upwards

Answer

To determine the direction of the current in the front face of a circular wire that behaves like a north pole, we can use the right-hand rule, which is a common method in electromagnetism.

### Step-by-Step Solution:

1. **Understand the Concept of Magnetic Poles**:
- A circular wire carrying current generates a magnetic field around it. The direction of the current flow determines the orientation of the magnetic poles.

2. **Identify the Right-Hand Rule**:
- The right-hand rule states that if you curl the fingers of your right hand in the direction of the current flow, your thumb will point in the direction of the magnetic field lines.

3. **Determine the Current Direction for North Pole**:
- For the front face of the circular wire to behave like a north pole, the current must flow in such a way that the magnetic field lines emerge from that face.

4. **Apply the Right-Hand Rule**:
- If we want the front face to act as a north pole, we need to position our right hand such that the fingers curl in the direction of the current. If the fingers curl anti-clockwise when viewed from the front, then the thumb will point outward, indicating that the front face is indeed a north pole.

5. **Conclusion**:
- Therefore, for the front face of the circular wire to behave like a north pole, the direction of the current must be anti-clockwise when viewed from that face.

### Final Answer:
The direction of current in the face of the circular wire is **anti-clockwise**.
