A permanent bar magnet in a cupboard catch has its north pole labelled N and its south pole labelled S. A curved field line outside the magnet passes through points P and Q. The neighbouring field lines are closer together at P than at Q. Which statement about the magnetic field is correct?
The field points from N towards S and has the same strength at P and Q
The field points from S towards N and is stronger at Q than at P
The field points from S towards N and is stronger at P than at Q
The field points from N towards S and is stronger at P than at Q
