Been messing around with Electromagnetic motors of my own design for 3 1/2 years never truly replicated anything I learned about wire gauges by trial and error, and I don't do math, yet I can make awesome and powerful things that can do all of what the brand name can do even if I don't know what it does. I'm sure in the kinetic realm this means you have to have a spiny bit a rotor something that cost to move without this you can't even enter the over unity competition spin your wheel and run/charge the same battery you win.
