Magnetic Effect of Current and Magnetism

This chapter discusses the concept of the magnetic field. We will study the applications of Biot-Savart's law and Ampere's circuital law. We will understand the motion of a charged particle in combined electric and magnetic fields.

This chapter discusses torque in a moving coil galvanometer. It also highlights the conversion of galvanometer into ammeter and voltmeter via experimental activities.

This chapter describes the earth's magnetic field. It explains the magnetic dipole moment of a current loop. We derive the formula of the potential energy of a magnet kept in a magnetic field. It also explains how to draw the magnetic lines of force.

This chapter discusses the classification of substances according to their magnetic behaviour. It highlights the properties of dia, para, and ferromagnetic substances. It also explains the process of demagnetisation.
