Self-Runner NS Coil Pulse Motor Live Video Stream. It's been going for months!

When my coil is dry and the reading is 0-1mV the coil still drives the compass crazy when I pass it by the coil.

Where is this magnetic energy coming from then?

I would suspect there is remanence in the core and steel wire. With higher iron and low carbon in the core the effects should be smaller. You could take a fine needle or a tiny steel washer and see if the core or iron wire attracts it. If it doesnt then maybe the earths magnetic field is involved.
I need to acquire a compass and do a plain totally non magnetic steel core to see if the compass is disturbed by the core..

I'm sure it will be.  When I speak of testing the electro magnetic effects of the coil, I mean controlling the magnetic effect by shorting the wires exactly like I show in this video:  http://www.youtube.com/watch?v=lcjxA7bYUp0

I think so too. The earths magnetic field should at least run on top of the iron cores skin even though its weak. I would think if the core were aligned with the earths magnetic north and south,the field lines would run the length of the core making it easier to pick up a magnetic field.

FYI my core is a ferrite rod that I had laying around.

If its a hard ferrite then you probably have remanence in it as well as the wire.
