· Connect a hand turned generator to a light bulb. Observe the light bulb when you...
· Rotate the generator slowly

The induced voltage decreases
· Rotate the generator quickly

The induced voltage increases
3. Increase the strength of the magnet

The induced voltage increases
4. Increase the number of turns in the coil

The induced voltage increases
