A bar magnet lies along an east–west line inside an opaque box, with one pole close to each end of the box. Point P is immediately outside the east end. A small bar magnet is positioned so that its south pole is at P. The force on this south pole is towards the east.
Ignore the Earth's magnetic field. The magnetic field being considered is the field produced by the magnet inside the box; neglect any effect of the small test magnet on this field.
Explain the direction of the magnetic field at P.
State which pole of the bar magnet is closest to the east end of the box. Explain your answer.
