Yesterday I posted I would do a experiment, the idea is to show which electrodes interact the best picking up earth currents, and the results are surprising.
I used a COPPER as the North and positave electrode.
Aluminium, Copper, Steel and Magnesium coated rod.

Copper Positave and Aluminium produced the best results
                                        AT REST   MOVEMENT   ANALOG
COPPER           MAGNESIUM = 36.0mv     71.0mv        needle slight movement
COPPER           STEEL         = -2.9mv     40.0mv        needle not moveing

COPPER           COPPER       = -20mv      -10mv          needle not moveing

COPPER           ALUMININUM = 80mv       198mv          needle swinging wildly back and forth

Results =
1st Copper as Positave, Alumininun as Negative  produces best results
2nd Copper as Positave, Mag as negative
coper and coper, copper and steel  = zilch

You will all have to step into the "way back" machine to remember this post from last November.

Were all the pieces of metal used in this experiment the same size?
I'm referring to surface area and not just length.

I've never seen where copper and aluminum produced the best effect.
So if one of the pieces of metal was larger (more surface area) than the other, then that might be an important fact that we could try to exploit.

Hey fellow experimenters!
I have been doing some work with aluminum and pultruded carbon rods, which seem to work just fine for electrical conduction for my battery 'projects'. Cool thing is they don't corrode. At least I'm pretty sure they don't, I'm still waiting for 'long term' results... ;)
I'm not sure if they conduct exactly as well as copper but I can't tell the difference with my cheap digital VOM set on the milivolt setting...
Play safe!
