A circular loop of wire lies in the plane of the page and carries a current in the clockwise direction. What is the direction of the magnetic field at the centre of the loop?

Step-by-step solution

1. Apply the right‑hand rule: point your fingers along the direction of the current (clockwise).
2. Curl your fingers around the loop; your thumb points in the direction of the magnetic field at the centre.
3. For clockwise current, the thumb points into the page (towards the observer).
4. Thus the magnetic field at the centre is directed into the page.
5. The correct option is "Into the page".
