Electromagnetic Induction and Alternating Currents

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.

This unit discusses the concepts related to electromagnetic waves and their production. We will learn about electromagnetic spectrum, emission spectra, absorption spectra, and Fraunhofer lines with the aid of experiments.
