Below we have provided some of the important points to remember from NCERT Class 12 Physics chapter 4 to prepare for the board exams:

- Electricity and magnetism have been known to humankind for more than 2000 years.
- In 1820, Danish physicist Hans Christian Oersted discovered the existence of a relation between electricity and magnetism through a lecture demonstration.
- With further intense experimentation, in 1864, James Maxwell unified and formulated the laws obeyed by electricity and magnetism.
- Through the Moving Charges and Magnetism chapter, students will learn how the magnetic field forces moving charged particles, like electrons, protons, and current-carrying wires and how currents produce magnetic fields.
- Like in the sci-fi movies, students will also learn about a cool machine named Cyclotron, created to accelerate charged particles or ions to high energies and a case study based on that.
- The Moving Charges and Magnetism chapter will have some interesting experiments proving the phenomenon of electromagnetism.
