Question

at what place of the magnet are the magnetic field lines denser?

Answer 1

place of the magnet where the magnetic field lines denser is near the poles

Answer 2

The magnetic lines of a magnet are denser near the poles of the magnet.

Explanation:

As given in diagram below shows the magnetic field ejected from a common pencil magnet with magnetic lines coming out of the magnet in an elliptical pathway from North Pole (N) to South Pole (S), as we can see that the pathway is denser at the poles of the magnet denoted by (N) and (S) rather than at the sides. Therefore, the magnetic lines of a magnet are denser in the poles of the magnet.
