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.

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 wire coiled around the iron nail, and thus the electromagnet will not be activated to attract the paper clips.
