Time-varying magnetic field creates an electric field, this is called _.
Correct answer: C. Electromagnetic induction
- A. Electric induction
- B. Magnetic induction
- C. Electromagnetic induction
- D. Dipole induction
Explanation
Option C is correct since electromagnetic induction is a process in which a conductor is put in a particular position and the magnetic field keeps varying or the magnetic field is stationary and a conductor is moving. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor.

About Faraday's Law
Faraday's law states that an induced electromotive force equals the rate of change of magnetic flux linkage through a circuit. Questions cover changing field, area, angle or motion, the negative sign associated with Lenz's law, and the distinction between induced emf and the current that may flow in a closed circuit.
