Question

Use the image to answer the question below.

More coils are produced when the wire is wrapped tightly around the iron core.

What will happen to the property of the electromagnet with an increasing number of coils?

picture of a battery with a wire attached to the negative terminal then winding around an iron core. The second end of the wire goes back to a switch that is open. The open switch is connected to the positive end of the battery.

The electromagnet will lose its magnetic properties.
The electromagnet will lose its magnetic properties.

The electromagnet will become more powerful.

Answer 1

The correct response is:

**The electromagnet will become more powerful.**

Increasing the number of coils around the iron core enhances the strength of the magnetic field generated, making the electromagnet more powerful.
