Physics Chapter 15 2nd Year Electromagnetic Induction MCQs with Answers

If you are looking for Physics Chapter 15 2nd Year Electromagnetic Induction MCQs with Answers then you are on the right page and here you will get important MCQs for preparation of the Entry Test. This chapter is about inducing Electromagnetic current. In this chapter, we will study inductance. Faraday’s law is very important to study induction. Self-inductance and its effects and dependence are discussed. The inductor is a device used to store energy. Lenz’s law is very important to study this phenomenon. After this, we study the working of transformers. Step-up and step-down transformers are the two types of transformers. During the supply of electricity, there are several losses done including line losses and eddy current. This is a brief summary of Electromagnetic Induction. To check the MCQs for entry test, scroll down and have a look at the important ones.
