Madison did an experiment to learn about electromagnets and permanent magnets. She used a nail wrapped with a copper wire attached to a battery. She also used a long bar magnet. To test the strength of the two magnets she tried to pick up steel paper clips to form a chain.

Madison found that both magnets could pick up 5 paper clips, but if she changed the number of times the wire was wrapped around the nail she could change how many paper clips were in the chain picked up by the electromagnet. Increasing the number of times the wire was wrapped around the nail increased the number of paper clips the electromagnet could pick up. The permanent magnet always picked up 5 paper clips.

Which argument is BEST supported by the information from Madison's experiment?
