Best answer

(i) Maximum magnetic field is in the region A and C.
(ii) 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.
