Question 19 • *KCPS Physics First (2027)

Georgia moves an unattached piece of wire back and forth over a magnet. Which best explains what will happen?

Answer
A
A current will not be induced because the wire moves through a magnetic field.
B
A current will be induced because the wire is not part of a closed circuit.
C
A current will be induced because the wire moves through a magnetic field.
D
A current will not be induced because the wire is not part of a closed circuit.

Explanation

Moving the wire through the magnetic field can create an induced voltage, but an electric current needs a complete, closed path to flow. Since the wire is unattached and does not form part of a closed circuit, a current will not be induced. The best choice is “A current will not be induced because the wire is not part of a closed circuit.”
