UP Board Class 12 Physics – Moving Charges and Magnetism
“Moving Charges and Magnetism” is an important chapter in UP Board Class 12 Physics that explains the magnetic effects produced by electric currents. The chapter begins with Oersted’s experiment, which shows the fundamental relationship between electricity and magnetism. Students learn how a current-carrying conductor generates a magnetic field and how this field interacts with other charges and currents.
A major focus of the chapter is the Biot–Savart Law, which helps calculate the magnetic field around current-carrying wires, loops, and solenoids. The concept of Ampere’s Circuital Law provides a simplified approach for highly symmetric magnetic field problems. Students also explore the motion of a charged particle in a magnetic field, which is essential for understanding cyclotrons and electric motors.
The chapter covers force on a current-carrying conductor, torque on a current loop, and the working principle of devices like galvanometers. Numerical problems, vector analysis, and diagrams help build strong conceptual understanding.
This chapter lays the foundation for upcoming topics such as Magnetism and Matter and Electromagnetic Induction.
