Correct answer: C. 1831
- A. 1830
- B. 1841
- C. 1831
- D. 1931
Explanation
Faraday's law of electromagnetic induction was deduced in the year 1831. It was formulated by the English scientist Michael Faraday in 1831. Faraday's law describes how a change in magnetic flux through a loop of wire induces an electromotive force (EMF) and therefore an electric current in the wire. This discovery laid the foundation for the development of electric generators and transformers.

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
