MAGNETISM

In this chapter, Magnetism, we learn about magnets and their basic properties. We study natural and artificial magnets, their different forms, and the law of magnetic poles. The chapter explains the directive property of a magnet, which helps us understand why a freely suspended magnet always points in the North–South direction. We also learn about induced magnetism and magnetic induction, showing how magnetic materials acquire magnetism temporarily. The concept of a magnetic field is introduced through magnetic field lines, along with their important properties. Further, the chapter helps us understand the Earth’s magnetic field, including magnetic poles, the magnetic equator, and neutral points. Overall, this chapter builds a clear foundation of magnetism using simple experiments, diagrams, and observations.
