The coils picked up a little or lot of paper clips at 5 coils around the nail? Why?
What is a little, because the magnetic field was still weak?

Two ways that you could make the electromagnet lab have worked better if you were not able to pick up any paper clips...
What is
1) Replace Battery
2) Sand off the insulator layer
3) Wrap more coils
4) Wrap coils tighter to the nail and the other coils
5) Make sure the copper was on the terminals (Button and Bullseye)
