Who discovered electromagnetic induction?

A Heinrich Hertz
B John Lewis Hall
C André-Marie Ampère
D Michael Faraday

Correct Answer: Michael Faraday

English physicist and chemist Michael Faraday''s many experiments contributed greatly to the understanding of electromagnetism. Faraday’s work on electrochemistry provided him with an essential clue for the investigation of static electrical induction. Electromagnetic induction is the induction of an electromotive force in a circuit by varying the magnetic flux linked with the circuit. This phenomenon was first noticed and investigated by Faraday; the law of induction is its quantitative expression.
