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.
The switch is turned on.
The switch is turned off.
There are not enough coils of wire around the iron nail.

The most likely conclusion to explain this result is that the switch is turned off. Electromagnets only exhibit magnetic properties when an electric current is flowing through the coil of wire. When the switch is turned off, the electromagnet is not activated and therefore no attraction is observed between the electromagnet and the paper clips.
