Question

Four plotting compasses are placed near a bar magnet. One compass appears like this:


What is a possible position for the compass? (Ignore any effects of the Earth’s magnetic field.)

Answer 1

Magnetic fields can be visually represented as magnetic field lines.
The direction of the north pole of a compass needle represents the direction of magnetic field lines. Magnetic field lines originate from the north pole of the magnet and terminate at the south pole. Hence, the correct compass will be 3.
