Canceling Lenz's Law - Methods

[alan]

Nice design. I think the zener is being used incorrectly.
also: the induced current that charges the cap will result in lenz law which works against the motion of the magnet.
The push of the second coil won't contain more energy than was induced so eventually it will slow down, but.. this all is according to conventional em/ee theory, so don't let _that_ discourage you, but keep it in the back of your head.
This is my view, feel free to correct me.

edit: Will the rotor be driven by a motor a la Peripeteia?
Maybe you can eliminate/delay lenz like Thane does in his setup (HV coil), so the energy is stored between the wires as an electric field instead of a (countering) magnetic field. ?

Nice diagram!
However, I have to agree with alan.

Hi Wattsup,

Yes,  there will be Lenz drag during the capacitor is charging. The inclusion of a Zener diode will let the capacitor discharge to as low as the Zener voltage so there will always be some voltage left in the capacitor, this would help reduce Lenz drag to a degree in case there would be a reed switch in series with the Zener diode. (Lenz drag is less when the capacitor is not charged from a totally discharged state but from some left over voltage level in it like the Zener voltage (maybe a few Volts?) in this particular case.

Without the switch the capacitor (hence the pickup coil) is continuously loaded by the Zener + pulse coil  and this would mean a constant drag on the rotor. The induced voltage for charging the cap should always be higher than the Zener voltage, to get a meaningful pulse at all and in case there is no switch to break the load circuit (i.e. the Zener + pulse coil) on the capacitor the voltage would always be as high as the Zener voltage and any further discharge current would be fed continuously to the pulse coil. This would cause the continuous drag on the rotor and ALSO a continuous pole on the pulse coil.

By including a reed switch the capacitor is able to charge up to the maximum voltage the induction constitues (strength of the magnets and the pickup coil's number of turns) and then the switch would suddenly discharge it through the Zener diode into the pulse coil (say to repel the rotor magnet away) and the capacitor would be discharged to the Zener voltage level from the max induced voltage.

(The Zener in fact dissipates induced power, and it should be tested whether it is worth using it at all,  the only benefit it would give at all  is not letting the capacitor discharge towards zero voltage so the Lenz drag would be less a little bit between the pickup coil and the rotor magnets.)

I hope I was understandable with this explanation, if not, please ask.

Hi folks, hi gyulasun. Ok thats interesting, all the other information and obvious advantages of the motor design get thrown out the window just because of one post and then the man falls off the face of the earth, how very interesting. Lets not forget this motor design uses both poles of coil directly with the flux compression, that alone makes this motor superior to anything else ive ever built, i dont know about anyone else. So even if there is no cemf reduction it doesnt really matter because this design makes practical use of air core coils by the flux compression and dual poles being used and by design no drag back to coils and all other benefits of not using cores.

peace, love, light

This site has a really good picture of Lenz law.  Just locate lenz law on the right hand side of the index.

From this we can study what happens in a simple alternator, namely a coil and a magnet that passes by.  As a magnet approaches a coil with a load attached, the magnet will encounter a repel force from the coil as induction occurs.  As the magnet begins to leave the coil, attraction forces occur as well. 

Now for some fun.  What if...
The load was not applied to the coil until the magnet is centered in the coil.  Then wouldn't current follow voltage by ninety degrees in the coil, allowing the lenz magnetic field to approach full strength (90 degrees later) to form a lenz attraction reaction a short time after the magnet starts to leave the coil?  This arrangement would reduce the overall power that is induced, but it may seriously reduce the lenz attraction drag by providing a gap between the magnet and the coil when maximum attraction occurs from the lenz reaction??  Do you think this would result in an advantage?
