23.2 Electrical properties of material
It has been in Chapter 16,page 439,that material can be grouped as conductors, semi-conductors or insulators as far as the property of electric current-flow along or through them is concerned . Another, but overlapping, method of grouping uses the magnetic property of materials. For most practical purposes, materials may be grouped as either 'magnetic or non -magnetic.
