Ok I replicated a switched magnet Robert Smith brought to our attention. Here is a video he did demonstrating this and along with how to build it. This is not an electromagnet. https://www.youtube.com/watch?v=n4YD8Nvyfa4

I think this has big potential for at least one of my own designs. I plan on doing a complete redesign a linear/rotary motor I built some years ago that showed potential. Like may other free energy device it could not overcome the gates. However this devise has the potential of eliminated those gates with very little power input. Im not going to shoot for a free energy devise if some how that happens than that would be just fantastic. But the electric car is here and the market for new technologies to make them better is astronomical. I can see a need for more powerful but also very efficient motors, so this is the goal Im setting out for this project.
Nothing new here, you can go here for more detailed
