Question

Draw the pattern of field lines due to a bar magnet. Mention any two properties of magnetic field lines
please answer correctly

Answer 1

magnetic field flow from south pole to north pole within the magnetic  always.
magnetic field lines never cross each other.

Answer 2

Explanation :

The electric field lines are shown in the attached figure. A bar magnet has two poles i.e. north pole and the south pole. The field lines start from the north pole of the magnet and terminate at the south pole.

The properties of magnetic field lines are as follows :

1. The field lines never intersect each other. This is because at the point of intersection there will be two directions of the electric field.
2. As we move away from the magnet the magnetic field strength decreases.
