Why are magnetic field lines crowded near the poles of the magnet?

(a) Describe an activity to show with the help of a compass that magnetic field is strongest near poles of a bar magnet. (b) Mention the direction of magnetic field lines (i) inside a bar magnet and (ii) ouside a bar magnet.

A magnet is cut into two parts by cutting it along its length. Is the crowding of the magnetic lines of force at the poles of the new magnet the same as it was in the old magnet ? Explain your answer.

The magnetic field lines inside a bar magnet

Choose the correct statement/s: (i) Magnetic field lines try to expand in length. (ii) Magnetic field lines repel each other laterally. (iii) Magnetic field lines attract each other laterally. (iv) Magnetic field lines are crowded in region where magnetic induction has least value.

The figure shows a bar magnet held vertical on a plane paper. The sketch of the magnetic field lines is shown. Can you identify the poles of the magnet?

Magnetic Field And Field Lines

In the figure here a paramagnetic sphere is located near south pole of a bar magnet . The magnetic dipole moment of sphere is

The three diagrams in the following figure show the lines of force (field lines) between the poles of two magnets. Identify the poles A, B, C, D, E and F.
