This chapter looks at the response of different materials to magnetic fields. Students study magnetic flux density, permeability, susceptibility, hysteresis and the characteristics of diamagnetic, paramagnetic and ferromagnetic substances.
This page covers Magnetic Properties of Meterials, chapter 17 of 25 in the Class 12 Physics syllabus set by the National Examination Board (NEB). 4 important questions for this chapter are available, each with a full solution.
For numerical and derivation-based chapters like this one, working through past NEB questions is usually more useful than re-reading notes alone — try solving each important question above before checking the solution, then compare your working step by step.
