Question

Magnetism at the centre of a bar magnet is
A. minimum B. maximum C. zero D. minimum or maximum

Answer 1

Magnetism at the centre of a bar magnet is zero.i.e option c

since it can be explained by that the magnetic field lines are originated fom pole and donot at centre

Answer 2

Magnetism at the 'centre of a bar magnet' is zero.

Answer - Zero (Option C)

Explanation:

• Magnetism is strongest at north and south poles of the magnet and weakest at the "centre of a bar magnet".
• This is because the "magnetic field lines" run parallel to the length of the magnet at the centre and run closer and denser at the poles.
• Each magnet is a dipole and its “force is proportional" to the "strength of the dipole" and rate at which the magnetic field changes.”
