Gina's class makes a circuit using a battery, a wire, and an iron core.

Question

Gina's teacher places a magnet next to the iron core of the circuit and the magnet begins to move without anyone touching it. Why does the magnet move?
A.
The battery that is connected to the circuit is a magnet that transfers energy to the iron core.
B.
The magnetic energy running through the circuit causes the iron core to give off electricity.
C.
The electricity running through the circuit causes the iron core to have magnetic properties.
D.
The iron core uses the heat being transferred from the battery to make magnetic energy.

Answer 1

The correct answer is:

C. The electricity running through the circuit causes the iron core to have magnetic properties.

When electricity flows through the circuit, it generates a magnetic field around the iron core. This means that the iron core becomes magnetized due to the electric current, and its magnetic field can interact with the nearby magnet, causing it to move.
