Electromagnetic Induction — Quiz

Question 4 • Physics

Tonya is modeling the discovery of electromagnetic induction. Which procedure should she use?

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

Explanation

Electromagnetic induction occurs when a changing magnetic field causes an electric current in a circuit. Moving a magnet into a coil changes the magnetic field through the coil, and the closed circuit lets the induced current flow. An open circuit would prevent current from flowing, while the compass procedures do not model induction.
