Explain the mechanism by which AC (alternating current) through the primary circuit of a transformer produces an alternating voltage and current in the secondary coil. Then explain why this would or would not work with DC (nonalternating current) in the primary coil.

The right answer for the question that is being asked and shown above is that: "It takes a changing magnetic field to create an electric field. So if it was DC the magnetic field from the primary would be unchanging, and no voltage would be induced."
