Part A

• What can you conclude from your recorded observations?

Address the following questions: Why does moving the magnet result in a

deflection of the galvanometer? How does the direction of the movement

affect the direction of deflection?

Part B

• What can you conclude form your recorded observations? What does the iron core do? Can you now explain the purpose of using an iron core in a transformer?
  • Graph of average deflection vs decreasing length inside the coil

Part C

• What does the graph imply about the relationship between these two quantities? Does this make sense i.e. is it in keeping with the theory of Electromagnetic Induction?

DISCUSSION AND COMMENTS

• What are possible sources of error in this lab?
• Use your deductions from this lab to answer the following question. A bar magnet is dropped through a horizontal loop of wire connected to a galvanometer. The North pole of the magnet is closer to the wire. Describe what you would observe on the galvanometer as the magnet approaches the loop and exits the loop.
