Now for the test. Connect the galvanometer’s alligator clamps to the two nail terminals. Keep the compass about a foot away from the magnet. Again, as in Experiment 2, have the galvanometer coil lined up with the compass needle.

     Set the generator in the wind or in front of a fan. (Or wrap a couple feet of string around the shaft and pull upward, like trying to start a power lawn mower.) When the shaft turns, you’ll see the compass needle deflect. This demonstrates that electricity can be produced from the wind.
