Electromagnetic Induction: Class 12 Physics (CBSE) important questions and practice
Electromagnetic Induction is chapter 6 of 14 in CBSE Class 12 Physics. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Faraday's experiments and laws of electromagnetic induction
- Lenz's law and conservation of energy
- Motional EMF
- Eddy currents and their applications
- Self-inductance and mutual inductance (solenoid, two coaxial solenoids)
- AC generator: principle, working and expression for induced EMF
What examiners usually ask
- State Lenz's law and show that it is consistent with the law of conservation of energy
- Derive the expression for the motional EMF induced in a conductor moving in a uniform magnetic field
- Derive the expression for the self-inductance of a long solenoid; a coil of 100 turns has flux changing from 0.1 Wb to 0.3 Wb in 0.2 s, find the induced EMF
Exam tip
Lenz's law with energy conservation, motional EMF (E = Blv) and the AC generator derivation E = NBA omega sin(omega t) are the standard derivations; in numericals include the negative sign of Faraday's law only when direction is asked.
