Which describes michael faraday’s work with electricity and magnetism? a. he discovered electromagnetic induction after seeing a compass needle deflected by a flowing electric current. b. he discovered electromagnetism after seeing a compass needle deflected by a flowing electric current. c. he discovered electromagnetic induction after seeing a changing magnetic field generate an electric current. d. he discovered electromagnetism after seeing a changing magnetic field generate an electric current.

Explanation :

Michael Faraday is known for the discovery of electromagnetic induction. According to Faraday's law, the changing magnetic flux produces an EMF which is given by :

is the emf produced.

is the magnetic flux.

We know that emf is

So, the correct option is (C) " He discovered electromagnetic induction after seeing a changing magnetic field generate an electric current" .

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

option number c is the right answer.
