Leisha thought of three ways she could change her investigation:
1. Observe the direction the bar magnet moves when she brings it near the end of the nail.
2. Observe how many paper clips she can attract to the end of the nail.
3. Connect each wire to the opposite end of the battery as before.
She wants to know how changing the direction of electric current in an electromagnet affects the magnetic

Part A: Identify which of these modifications Leisha should use in her new investigation.
Part B: Explain how each modification you selected will help her meet the goals of her investigation.
