Question

Which of the following statements regarding the magnetic field produced by a bar magnet is incorrect?

• A. Magnetic field lines are continuous in nature
• B. Magnetic field lines have both magnitude and direction
• C. Magnetic field lines intersect each other at the poles of a bar magnet
• D. Magnetic field lines are stronger at the poles and weaker near the centre of a bar magnet

Answer 1

The correct option is C

Magnetic field lines intersect each other at the poles of a bar magnet

One of the characteristic properties of magnetic field lines is that they never intersect each other. It is because of the fact that if two magnetic lines of force were to intersect, then at the point of intersection a compass needle would point toward two different directions, which is impossible.
