Another experiment to conduct:

1) Install a ferrous pipe into the ground
2) Run a steel line from the pipe to one node of a galvonometer
3) Run a steel line from the second node of the galvonometer to a carbon rod
4) Point the carbon rod along various axes and at various positons and observer the galvonometer readings

And another one - the human compass:

(taken from a Laura Lee interview with Gerry Vassilatos and Michael Theroux from July or August of 1993 entitled: Vril Energy, in the last 5 minutes of the interview)

1) Take a piece of aluminum foil, cut it in a long diamond shape, crease is down the center, pivot it on a needle point
2) Take a container full of water, such as a repurposed salad dressing bottle
3) Tape the needle to the container such that the needle is verticle, place the folded-aluminum-diamond on the needle point
4) Suppress wind, air flow, etc.
5) Point your hand at the 'human compass' from various positions and observe
6) Leave the room and observe the natural direction of the human-compass
