A student wraps copper wire around an iron nail. Then she connects the ends of the wire to a battery, making an electromagnet. She notices that if she wraps more coils of wire around the bolt, then her electromagnet can pick up more paper clips. What conclusion can she draw?(1 point)
Responses
More coils of wire increases the density of the copper wire

The correct conclusion the student can draw is:
**More coils of wire increases the strength of the electromagnet.**
This is because increasing the number of coils around the iron nail enhances the magnetic field produced by the current flowing through the wire, resulting in a stronger electromagnet capable of picking up more paper clips.
