Answer 1

When a magnet is put inside two coils of wire, the voltage will increase by a factor of two.

Step-by-step explanation:

When a magnet is put inside one coil of wire, a voltage is produced due to electromagnetic induction. This occurs because the changing magnetic field generated by the magnet induces an electric current in the wire. If the magnet is put inside two coils of wire, the voltage will increase by a factor of two. This is because the magnetic field will induce a current in each coil separately, effectively doubling the overall voltage.
