1.	The given magnet is divided into three parts A, B andC Name the parts where the strenght of the magnetic field is : (i) maximum(ii) minimum How will density of maganetic field lines differ at these parts ?
Answer» Solution :Maximum magnetic field is in the region A and C. (ii) Minimum magnetic field is in the region B. This is because A and C are magnetic poles and have maximum NUMBER of magnetic field line which DETERMINE the intensity of magnetic field while B is centre of the magnet that has no mag- netic field LINES. So intensity of magnetic field NEAR B is ALMOST zero.
