Chapter 4 Moving Charges and Magnetism has good marks assigned in the Board exams. The Moving charges and Magnetism chp 4 include many interesting topics like magnetic forces, magnetic field, the direction of magnetic force in the current-carrying coil with different cases, etc. These concepts are not only important in your board exam but also for students who are aiming for IIT-JEE, NEET exams as well.

Students must start with Class 12 Physics Chapter 4 important questions after revising the chapter. Let us have a look at some main points of Chapter 4:

• The chapter consists of different derivations like ampere circuital law, the force between two parallel current-carrying wires, etc.

• Chapter 4 mainly focused on explaining the idea that electric and magnetic fields are correlated to one another. Since the beginning it was assumed that electric fields and magnetic fields are independent of each other.

• We come across concepts such as magnetic force, Lorentz force which is a piece of evidence about electric and magnetic fields which are related to each other.

• We study cyclotrons, solenoids, moving coil galvanometers, etc.

These are a few key points to be remembered while jumping into the practice of Chapter 4 Physics Class 12 important questions.
