Coil 1, connected to a 100 Ω resistor, sits inside coil 2. Coil 1 is connected to a source of 60 cycle per second AC current. Which statement about coil 2 is correct?
A) No current will be induced in coil 2.
B) DC current (current flow in only one direction) will be induced in coil 2.
C) AC current (current flow in alternating directions) will be induced in coil 2.
D) DC current will be induced in coil 2, but its direction will depend on the initial direction of flow of current in coil 1.
E) Both AC and DC current will be induced in coil 2.

When an AC current flows through coil 1, it generates a magnetic field that alternates in direction at a frequency of 60 Hz. This changing magnetic field induces an AC current in coil 2 according to Faraday's law of electromagnetic induction. Therefore, AC current flows in coil 2.
