The given bar magnet is divided into three parts X ,Y ,Z

Name the part where the strength of magnetic field is

  1. maximum 
  2. minimum

How will the density of magnetic field lines differ at these parts?

Expert Answer:

Maximum magnetic field is in the region A and C. 
Minimum magnetic field is in the region B.  This is because 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 that has no magnetic field lines. So intensity of magnetic field near B is almost zero
