This video starts with a magnet power demonstration, and then I move on to introduce my stator arm assembly and describe its various parts. The stator arm is an integral part of the PVC frame, and is used to hold the stator magnet at a specific height, angle, and alignment above the bicycle wheel rim. This greatly reduces operator effort which is otherwise required when the stator magnet is hand held. The greatest effort expended, when the magnet is hand held, is that which is required to keep the magnet at a steady height, and to prevent it from slamming down onto the rotor (wheel rim) or the rotor magnets. The stator arm also allows the stator magnet to be positioned closer to the rotor magnets than would be possible when hand held, and this affords increased thrust because of the increases in attraction and repulsion forces that are realized.

In this video, I show how the magnets can be easily repositioned on the steel bicycle wheel rim in order to test a different layout configuration. Whereas the magnets were previously configured in groups with all north facing up, I now configure the groups with NSNS alternations. I also use a compass to show the rotor magnet orientations, and to show how the hard drive magnet is magnetized.
