The diagram shows the shape of the magnetic field lines near a current-carrying conductor. The current in the conductor is into the plane of the diagram. Which row correctly states the direction of the field lines and compares the strengths of the field at points P and Q?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

Adirection of field lines: clockwise, the field is stronger at: P

Bdirection of field lines: clockwise, the field is stronger at: Q

Cdirection of field lines: anticlockwise, the field is stronger at: P

Ddirection of field lines: anticlockwise, the field is stronger at: Q

✓ Correct answer

A: direction of field lines: clockwise, the field is stronger at: P
