Confirming the Delayed Lenz Effect

[conradelektro]

My magic black drive coil from a 12V relay, just in case someone wants to use a similar coil. (Note, this is not a magic generator coil, just a magic drive coil).

I am not a sales person of www.conrad.at, but I got it from them. Any similar type will do, the coil should be longish with a DC resistance of 250 to 300 Ohm.

It will not produce a lot of torque in a pulse motor, but it allows efficient driving.

The housing and the metal bar coming from the back of the coil to the contacts in the front has to be removed by help of a fine hack saw. I damaged the first coil, but then I saw how to do it (use a vice to hold the relay when working on it).

@Farmhand:


A question: Won't your neo's deteriorate by driving them in "repulsion" continually? If they do "wear out", then it would be disappointing to have to replace them periodically.

@Farmhand: I like the Three-Coil-Drive-Arragement! Another nice idea which I will try one day.

For the people who are interested, Version 1 of my magnet spinner did 8400 rpm with less than 0.5 Watt.

The drive circuit can be seen in my Reply #1202 on: April 23, 2013, 01:34:13 PM.

I don't know but I doubt it would do anything to them that sticking them on a fridge door wouldn't do anyway. If the energy leaves the magnet it must go somewhere and if there is no heat chances are it would go to rotation energy or recovery energy.

Nothing lasts for ever.
