Question 7 – Permanent and induced magnetism, magnetic forces and fields - Questions

Figure 1 shows the magnetic field lines in the region between two identical bar magnets with their North ( $N$ ) poles facing each other.

Magnetic field lines between two facing North poles

Which two statements are true for this magnetic field configuration?

A: The magnetic field strength at point $Q\,$ is greater than the magnetic field strength at point $R$ .
B: At point $P$ , the net magnetic flux density is zero.
C: A small North magnetic pole placed at point $Q\,$ would experience a magnetic force directed towards the nearest pole face.
D: If the magnets are pushed closer together, the magnetic field lines will cross near point $P$ .
E: The magnetic field is uniform in the region surrounding point $P$ .
