1) Go to the following page:
http://micro.magnet.fsu.edu/electromag/java/generator/dc.html
using your own words, briefly explain the operation of the device seen in this page.
What is the purpose of the split ring seen in the animation?
Explain the graph.
2) Go to the following page:
http://micro.magnet.fsu.edu/electromag/java/generator/ac.html
Explain the operation of this device.
What is the difference between this equipment and a DC generator.
3) Go to the following page:
