Moving Charges and Magnetism

A MOVING charge creates a MAGNETIC field. And a magnetic field exerts a FORCE on a moving charge. This chapter explores the intimate connection between electricity and magnetism — leading to the Biot-Savart law, Ampere's law, the force on a current-carrying conductor, and the moving coil galvanometer. CBSE Class 12 Physics Chapter 4.
