Moving Charges and Magnetism | Chapter 4 | NCERT | CLASS 12 | LECTURE 5 |

In this video, we explore Chapter 4: Moving Charges and Magnetism from the NCERT Class 12 Physics textbook. This chapter introduces the connection between moving charges and the magnetic fields they generate, forming a core part of electromagnetic theory. We discuss key concepts like the magnetic force on moving charges, the motion of charged particles in a magnetic field, and the Biot-Savart law. The video explains Ampere's Circuital Law and its applications in determining the magnetic field around current-carrying conductors like straight wires, solenoids, and toroids. Additionally, it covers the force between parallel currents and how it leads to the definition of the ampere. The working principle of the moving coil galvanometer and its use in measuring current and voltage are also explained in detail. This session includes theoretical explanations, numerical problem-solving techniques, and real-life applications to make the learning experience engaging and comprehensive. Ideal for board exam preparation, JEE, NEET, and a deeper understanding of electromagnetic concepts.
