The given magnet is divided into three parts A, B and C.
Name the parts where the strength of the magnetic field is:
- maximum
- minimum
How will density of magnetic field lines differ at these parts.
Answer:
- Maximum magnetic field is in the region A and C.
- Minimum magnetic field is in the region B.
Reason: A and C are magnetic poles and have maximum number of magnetic field lines which determine the intensity of magnetic field while B is centre of the magnet has no magnetic field lines. So intensity of magnetic field near B is almost zero.
