Question

georgia moves an unattached piece of wire back and forth over a magnet. which best explains what will happen?
a current will be induced because the wire moves through a magnetic field.
a current will not be induced because the wire moves through a magnetic field.
a current will be induced because the wire is not part of a closed circuit.
a current will not be induced because the wire is not part of a closed circuit.

Explanation:

According to Faraday's law of electromagnetic induction, for an electric current to be induced in a conductor, there must be a closed circuit. When the wire is not part of a closed circuit, even if it moves through a magnetic field, there is no continuous path for the electrons to flow. So, no current is induced.

Answer:

A current will not be induced because the wire is not part of a closed circuit.
