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

all the end of the divided magnet from a single magnet will have same strength.. magnetic field lines are originate from the ends of the poles therefore magnetic field lines differ at the end pole of the magnet. as strength of all three magnet is same so therefore the magnetic field lines will also be same and their density also be same..
