Question 14 • TX-Physics B

Craig is modeling the discovery of electromagnetism. Which procedure should he use?

Answer
A
moving a magnet into a coil of wire in a closed circuit
B
moving a magnet into a coil of wire in an open circuit
C
bringing a compass near a wire that has no electric current
D
bringing a compass near a wire that has an electric current

Explanation

The discovery of electromagnetism showed that an electric current creates a magnetic field. Craig should bring a compass near a wire carrying current; the compass needle will respond to the field. Moving a magnet into a coil demonstrates electromagnetic induction instead.
