The law of electromagnetic induction is related:
Correct answer: B. Faraday
- A. Lenz
- B. Faraday
- C. Coulomb
- D. Ampere
Explanation
The law of electromagnetic induction is related to Faraday.The law of electromagnetic induction, also known as Faraday's law, is formulated by Michael Faraday. Faraday's law states that a changing magnetic field induces an electromotive force (emf) in a closed circuit. This principle is fundamental to the understanding of electromagnetic induction and its applications in generating electric power, transformers, and many other electrical devices.

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.
