Tonight I tried out my latest version of the magnetic propulsion device. It consists of a 12 inch aluminum cake pan with 6 off the shelf electromagnets. The main battery of electromagnets consists of 4 electromagnets with a 3/8 inch bolt through them. An Arduino and relay shield control the polarity of these electromagnets. The Arduino switches their polarity via a TV IR remote control and receiver circuit on a breadboard. When the north end of this battery of electromagnets turns the aluminum pan so that the magnets are as far north as they will turn we reverse the polarity and the aluminum pan rotates in a circle.
It is a motor with the Earth as it's stator or permanent magnet. But it has 2 more electromagnets next to each end of the main battery of electromagnets. These magnets alternate on and off in such a way that they match the polarity of the main battery of the magnet when it is north at their respective ends of it.
They increase the power of the rotation on one half of the circle but do so constantly. I believe it transfers some of the momentum of the rotating device in such a way that it moves in a line.
This is one of the best versions I have come up with so far. As can be seen in the below video it moves the device about an inch in the first minute and about 4 inches in the second minute.
In an earlier experiment I measured the force to move the device through the water at a similar rate of acceleration by taping a piece of string to the side of the tank and to the side of the aluminum pan and then weighing the piece of string. That is the weight of the string hanging between the side of the water tank and the device was enough to drag the device through the water ever so slowly. It weighed about 0.1 gram.
The electricity from the batteries is in the order of 40 watts. By comparison a Hall Effect thruster uses about 20,000 watts and produces about 3 units of gram force.
Were it not for the water resistance the device would spin much faster. Still we would not claim that the increase in speed would necessarily increase the force. (But it might)
The left side of the tank is pointing NNW approximately.
In theory this is all working but to really prove it works would require what is called a pendulum test. In such a test the device is attached to a long string and it is observed if the string swings to one side which would prove the presence of thrust.
Now to do such a test might require that the device be mounted on an axle with delicate bearings and very nicely balanced.
