NCERT Solutions for Class 12 Physics Chapter 6 Electromagnetic Induction

Electromagnetic induction is the production of an electromotive force that results from the movement of a conductor through a magnetic field. An electromotive force also results from the changing of magnetic flux in a closed-loop circuit. In such a wave, the electrical and magnetic fields potentiate each other. The chapter discusses magnetism and electricity together. Faraday’s law should be well versed and understood. Faraday’s law states that any change in the magnetic field of a current-carrying conductor results in voltage (emf) being induced in the conductor.

Lenz’s law states that there is always a counter-force opposing the induced emf. Both the laws are important from exam point of view.

Numerical problems from these concepts are often asked. While solving the numerical problems, please keep in mind the direction of induced emf and magnetic field. One can get a good understanding of these problems by solving practice.
