Jaeda designs two electromagnets of different strengths. The first electromagnet has an insulated copper wire wrapped around an iron nail many times before it is connected to a battery. The second electromagnet has its insulated copper wire wrapped around a similar nail a fewer number of times before it is connected to two smaller batteries as shown in the image. Jaeda tries to determine which electromagnet is stronger by bringing each near a bowl containing eight metal paper clips. She observes that both electromagnets attract all eight of the paper clips. How can Jaeda demonstrate that each electromagnet has a different strength

A. Place a metal paper clip on a table and slowly bring each electromagnet closer to the paper clip to see which can attract the paper clip from a greater distance.
B. Determine which electromagnet has its copper wire wrapped around its iron nail a greater number of times.
C. Add plastic paper clips to the bowl and check which electromagnet can attract both kinds of paper clips.
D. Reduce the number of paper clips in the bowl and find which electromagnet attracts more paper clips.
