Thanks for the heads up Floor.

He is just letting me know if the subject strays to far from original thread, how to reign it in. He knows I asked to keep the thread here so it can be moderated. You responded perfectly to the conversation we drifted to... as we drifted off subject, lol... but I don't mind on this one as long as it doesn't go completely orbo, lol. And the change in the toroid when the magnets are one to it does fit with my project as well. I'm learning as I go.

The point there is turning off the toroidal core .I don't think it will matter but I'm using a common 1 1/2 iron pipe and going for turn off .its like 4 inch's long .if successful I'll start using it on different iron structures. Once done playing around I'll take it apart to find out the wire length then rewind it to bifiler .if this works ...very long toroidal cores as pipes can be used . I'm doing both but I'm inclined to the toroidal turn off because so little energy is used .that Prof of concept and prof of over unity in the video with the led bank if looped could supply lights for anyone all the time .and charge a supper cap at night for a radio etc. Or a super cap flash light .I'm just trying to make them much bigger.all I see is tinny motors with low power .but over unity. If it works I could put neos on a child's marry go round and run it faster and faster .with out anymore energy than just turning it on and off . I wish he had used super brute LEDs they really light things up.

A little bit of an update. I have my new power supply but it is a bit confusing programming. I have pushed more power to the coils to test them, but the amp draw is not linear like it should be as I increase voltage. I've got a setting wrong or something. This power supply has features built in for charging lithium batteries amd stuff and I think I missed something trying to use it as just a simple power supply. For instance, at 18v is pushing 400ma, so is 19v, 20v, them at 21v it jumps to 450ma and 22v 500ma. So I think I've got a setting wrong somewhere. So I'm not ready to post numbers yet because something is wierd and i hasn't figured it out yet.


But... I am seeing something that is different than I expected. I expected for some reason, I would find a voltage that the internal permanent magnet field would all be released at once and there would be a sizable change in gauss for that voltage. But I am still not seeing that. It continues to be a steady increasing field for each voltage increase. I held a like pole magnet in front of the coil as I pulsed it, and I am still seeing a significant push compared to electromagnet alone. It seems to me like the permanent magnet is simply multiplying the field from the electromagnet and not just releasing all at once. Again, not a bad result, just unexpected to me. I'll know more soon.

It's not letting me post the link, but here is the power supply I ordered. It is 800w and up to 120v dc. Not bad for $35 on Amazon. Unfortunitely I haven't figured out all the settings yet.
