Question

According to Faraday's law of electromagnetic induction

• A. Eelectric field is produced by time-varying magnetic flux
• B. Magnetic field is produced by time-varying electric flux
• C. Magnetic field is associated with a moving charge
• D. None of these

Answer 1

The correct option is A

Eelectric field is produced by time-varying magnetic flux

Faraday's law of electromagnetic induction:

1. It states that, “Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced”.
2. If the conductor is a closed loop, current is produced. This current is called induced current.
3. It is the fundamental law of electromagnetism.
4. It describes the relationship between a magnetic field interacts and an electric circuit.
5. Electromotive force is the voltage produced by non-electrical sources.
6. Hence, according to Faraday's law of electromagnetic induction, electric field is produced by time varying magnetic flux.

Hence, option A is correct.
