4. Change the magnet to the original orientation and drag through the coil. a. What happens to the voltage and light bulb as the North Pole moves through the coil? b. What happens to the voltage and light bulb as the South Pole moves through the coil? c. Drag the magnet slowly through the coil and then faster trough the coil. What is the difference in the behavior of the light? Contrast how the voltage behaves in both cases.
