Correct answer: C. Russian
- A. Japan
- B. China
- C. Russian
- D. None of above
Explanation
Lenz was a Russian physicist. He was born in Dorpat, then part of the Russian Empire (now Tartu, Estonia), in 1804. Lenz made significant contributions to the study of electromagnetism and is best known for formulating Lenz's law, which describes the direction of the induced electromotive force (EMF) and current generated by electromagnetic induction.

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.
