Question

The given magnet is divided into a b c name the parts where the strength of the magnetic field is maximum how will the density of magnetic field lines defer at these points

Answer 1

strength will be max at the ends of a b and cand pattern of magnatic line of force will be same as bar magnet

Answer 2

the maximum strength is at the point near to the ends of magnet, the distance between which is 5/6 of the geometrical length of the magnet. so magnetic field is maximum at a,c.
