My dogs water bowl is one foot square and sits on top of a steel plate put there by the previous owner of my home. We have a large iron content in our soil here in Birmingham, Alabama and I noticed that when the soil in the water settled in the bowl over night that it formed a magnetic field pattern on the bottom of the bowl. I wonder if Mylows magnet turns out to be a true self runner it is due to it's magnet components interacting with the earths magnetic field? I would like to see the motor turned at 45 and 90 degrees to the earths surface to see if it still self starts and self runs. If this interaction turns out to be the case does that mean that the motor's torque is relative to the strength of the earths local magnetic field? That would make it just a laboratory curiosity with no practical use. Could the earths field be increased or replaced by a man made field to get more torque? I think it is well worth the trouble to try and self start and self run the motor at 45 and 90 degrees to see if this is a possibility.
Thanks,

Have you checked the steel plate to see if
it is magnetised, or contains residual magnetism.
Who knows what magnetic fields the plate was
exposed to before it was placed on the ground.

Yes I did that right off, it had none. I has long been known that large metal objects will become magnetized by the earth's magnetic field. They use to degauss ships during world war two on a regular basis so that German mines would not detect a change in the earth's magnetic field due to the ship being overhead.

Well it was just a thought, considering how much
magnets are used in the Bham steel industry.

For what its worth the plate has been there 50 years.
