1. Lab 10 Hints

2. Eddy currents (1A-1) Magnet Plate Metal pipe Plastic pipe Drop the magnet through the plastic tube and onto the paper plate, so as not to chip the magnet. Repeat with the metal tube. Address the questions in the lab manual.

3. Eddy currents (1A-2) Magnets Metal pendulum There are three different shapes for you to try

4. Eddy currents (1A-2) Extending the applications of (1A-1), can you explain how a soda machine determines which coin is which? Use the apparatus on the left. Where is the magnet on the scale on the right? Why is it there?

5. Eddy currents (1B-3)

6. Transformer (2A-1) and (2A-2) Transformer

7. Transformers
