Electricity and Magnetism

In this chapter, we will learn about the electric charge. It highlights Coulomb's law and the superposition principle. We will study the mechanism of the electric field in detail. It also covers the definition of electric dipole moment.

This chapter covers topics like electric potential and potential difference, electric potential energy, electric potential due to a dipole, capacitors and capacitance, energy stored in capacitor, and energy density in electric field.

This chapter sheds light on the current electricity. It discusses the sources of direct current, electric circuits, and detection of current through diagrams. It also describes Ohm’s law, electrical resistance, and conductors and insulators.

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.

The chapter deals with the formation of magnetic fields, magnetism and Gauss' law. It explains Earth's magnetism, magnetisation and magnetic intensity. The magnetic properties of different materials, permanent and electromagnets are also discussed.

This chapter explains the concept of electromagnetic induction. It explains Faraday's laws and the methods of changing the magnetic flux. We will also study the mutual inductance of two long coaxial solenoids.

In this chapter, we will learn the concept of alternating current. We will learn how to find the root mean square value of alternating current. It also briefs on the mechanism of electrical oscillations.
