After studying electricity in motion, the Physics 2nd Year Chapter 14 Electromagnetism MCQs with Answers is about the study of magnetic effect. The behavior of magnetic forces is discussed in detail. Here we will study the behavior of an electron when it is passed through a magnetic field. An important application to check the direction of the magnetic field is studied called Fleming’s Left-Hand Rule. The right-hand palm rule is also studied that is used to see the direction of the field, force, and current. There is a term Magnetic flux that is very important. There are different devices used to check the magnetic field. The galvanometer is one of them. Ampere’s law has a very big effect in Magnetic fields. So, this is a brief summary of Electromagnetism. If you are looking for the important MCQs for this chapter to prepare for the Entry test, then scroll down to get them.
