PERMANENT MAGNETS IN CIRCLE OR PENDULUM PROPULSION JUST AS GOOD AS ELECTROMAGNETS AND REQUIRE ALMOST NO ELECTRICITY
There is no doubt in my mind now that this principle works. A permanent magnet or an electromagnet rotating off center like a compass in Earth's Magnetic Field will work in LOE (Low Earth Orbit) and would have practical applications for at least de-orbiting small satellites at the end of their life cycles if not as well for adjusting orbits.
The video above is a small model made from a 12 inch aluminum pan, some N42 half inch diameter Neodymium magnets and a toy robot that rotates and is used for a servo. Clay is used for weight. The clay is blue colored.
Rotating the magnets as opposed to using fixed electromagnets gives great control of the little "boat" floating in a tank of water. It makes the boat turn in the low friction of the water pretty responsively. (Remember however the video is time lapsed at 6X)
Here is how and why it works.
* When the head of the toy robot is turned the magnet turns and then the whole aluminum pan model turns as the magnets act like a compass seeking to point north and south.
* As the aluminum pan turns it does not turn around the center of the torque from the magnet nor does it turn at the center of its mass but at a third point. Magnetic torque is extremely powerful compared to magnetic attraction of opposite poles at a distance. (Someone help me with the math and engineering.)
* The aluminum pan since it turns at a point not its center of mass has one part of it turning that is more massive than the other (The part on the side of the magnet). That creates centrifugal force. There is no claim here this defies any laws of physics since the magnetic interaction with Earth is an external force applied to the model)
* The centrifugal force pulls the aluminum boat in a line.
* This invention translates rotation from magnetic torque from a powerful compass into linear motion. (or force to be technical)
