Electromagnetic Induction

Question 9 • (OC27) Earth/Space Sci-2001310-S2-Nelson

Which describes Hans Oersted’s work with electricity and magnetism?

Answer
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

Oersted found that an electric current deflects a nearby compass needle, showing a connection between electricity and magnetism called electromagnetism. Electromagnetic induction—the generation of an electric current by a changing magnetic field—was discovered later by Michael Faraday. Therefore, the correct choice is “He discovered electromagnetism after seeing a compass needle deflected by a flowing electric current.”
