The scenario that will produce a current in the wire is:
**D. The magnet is moved back and forth within the coil of wire.**
This is due to electromagnetic induction, where a changing magnetic field within a coil of wire induces an electric current. The movement of the magnet relative to the coil creates a changing magnetic flux, which generates a voltage and consequently a current in the circuit.
**D. The magnet is moved back and forth within the coil of wire.**
