In this section you will learn about magnets and magnetism. It is a very important chapter. There will be about 3 questions 1 Very small type, 1 short answer type and one long answer type. In this chapter you will study magnetism, natural magnet, artificial magnet, properties of magnet, coulombs law, magnetic dipole, magnetic dipole moment, magnetic field due to magnetic dipole on axial line and equatorial line, torque acting on a magnetic dipole, potential energy due to magnetic dipole in a uniform magnetic field, current carrying loop, Gauss law in magnetism, magnetic moment of an atom, Earth's magnetism, magnetic meridian and Geographic meridian.
