Chapter 4 – Moving Charges and Magnetism
Chapter 4 of NCERT Physics Class 12 explains how moving electric charges produce magnetic fields and interact with them, forming the basis of electromagnetism. It introduces the concept of current as the flow of charges and describes the magnetic field around current-carrying conductors using rules like the right-hand thumb rule. The chapter also covers important laws such as the Biot-Savart Law and Ampere’s Circuital Law, which help calculate magnetic fields in different configurations. Additionally, it explains the force experienced by moving charges and current-carrying conductors in a magnetic field, along with the concept of torque on a current loop, which is essential for understanding the working of devices like electric motors. and it is important for Class 12 board exams and competitive exams like NEET and JEE.
