An electromagnet is built using a 9-volt battery connected to a switch via conducting wire that is coiled around an iron nail. A pile of metal paper clips is moved close to the iron nail, yet no attraction is apparent between the electromagnet and the paper clips. What is the most likely conclusion to explain this result?(1 point)

The paper clips are made of a nonmagnetic metal.

There are not enough coils of wire around the iron nail.

Answer 1

The most likely conclusion to explain the lack of attraction between the electromagnet and the paper clips is: The switch is turned off.

If the switch is off, no current flows through the coiled wire, and therefore the iron nail will not become magnetized to attract the paper clips.
