Isabella makes an electromagnet by wrapping copper wire around an iron bolt and then connecting each end of the wire to a battery. She observes that the more times that she wraps the copper wire around the bolt, the more paper clips her magnet can pick up. What does she conclude in this experiment?(1 point)
Responses
