Physics Revision Notes for Class 12 for Chapter 4 Moving Charges and Magnetism

Although we have known both electricity and magnetism for about 2000 years now, it was only 200 years ago we realised that they were intimately related. The chapter explains the relationship between magnetism and electricity in detail.

CBSE Notes Class 12 Physics Chapter 4 Moving Charges And Magnetism

In this chapter, one learns about the following topics:

  • The force exerted by the magnetic field on moving charged particles like protons, electrons and current-carrying wires.
  • How magnetic field is produced by a current carrying conductor
  • How particles are accelerated to high energies in cyclotrons
  • How voltages and currents are detected by a galvanometer
