Answer: The correct answer is "Move the magnet up and down near one of the coils".
Explanation:
There is a magnetic field around the current carrying conductor.
If the magnet is moved up and down near the coils then the electric current will be induced through the copper wires. The electric current can be induced by changing the magnetic field across the coil.
In the given problem, Theresa has a magnet and two coils of tightly bound copper wire. To induce an electric current in one of the copper wires, move the magnet up and down near one of the coils. The electric current can be induced in the coil due to the relative motion between the coil and magnet.
Therefore, the correct option is (B).
