Canceling Lenz's Law - Methods

[Thaelin]

    There seems to be one thing about these magnets that all are not catching.
Now I am not going to say it doesnot work, it does. The actual make up of the
metal backing is a trade secret for sure. They will tell you so.
    The part missed is the make up of the magnet its self. This type of magnet
has 4 poles. Example below:

                 NNNNNSSSSS
                 SSSSSNNNNN
           XXXXMETAL-BACKINGXXXX

    This makes one side of the circuit complete and the other open. Take 4 mags
and make the setup as above and stick to a backing plate. With standard metal
you will still have some attraction to the back side but very little. I used a 1/16"
galvanized metal for the backer and 4 grade 8 mags.

Hi folks, hi Gyula. That explains it, I was never able to see that website because I discovered the forum thread apparently too late, always wondered why my registering to his site went nowhere. i assume his pulse motor forum is dead now. Anyway, I am setting up a prony brake bar to test it so I should soon have an idea of the efficiency. Although It must be said as im sure your aware, that because it uses both coil poles and has absolutely no back attraction to cores or any collapsing field effects causing drag (back emf) and limits the collapsing spike which is nice for keeping transistors alive. Now i cant say for sure that it lessens lentz (cemf) however i have noticed i can bring a cap thats being charged from collapsing field lower in voltage than in most pulse motors ive built which may indicate less counter voltage being induced. Also if your aware of a motor called kawai motor, its efficiency which is claimed to be at least 315% derives its efficiency mainly from the fact that it cancels the flux of the stator coil that its leaving by diverting it away by energizing the next coil ahead eliminating drag back. Now isnt that what Garrys pulse motor does while still maintaining high density flux for coil attraction, unless a ferro core is needed to get the extra output seen in the kawai motor but if not then i would say garrys pulse motor probably is 200% at least based on this knowledge. Even the muller motor uses the same idea to get the extra output, eliminate the work required to move a magnet pole around. the difference here i think is that with garys design we can get practical torque levels by having that compressed permanent magnet field such that any other geometry would not be adequate to produce useful levels of shaft power.

peace, love, light

Thanks for the correction Thaelin. SkyWatcher, keep us updated.

Ok, so I guess we need more than just Mu-Metal to block a magnetic field. A magnet that sticks on one side and not the other is called a Halbach array after the name of the inventor.

Here is a link on how to build one. This could be very useful in any motor or maybe even a transformer design. I didn't realize you could setup magnets in a way that "blocked" the magnetic field only on one side. If you place one of these magnet arrays on a motor, it will have a tendency to spin longer than if you don't have a magnet. This is a form of free mechanical power.

@nali
it take only 10 or 20 watts, because it must not deliver any outut in electric or mechanic output !

Lenz's Law states:
An electromagnetic field interacting with a conductor will generate electrical current that induces a counter magnetic field that opposes the magnetic field generating the current.

A more elaborate experiment that demonstrates the same scientific principles can be done with a solenoid wrapped around a pop can. When the switch is closed. a capacitor in the circuit is discharged through the solenoid. Since the current varies in time, the magnetic field in the solenoid and the magnetic flux defined in the solenoid will vary in time. This variable flux also passes through the can inside the solenoid, inducing in it a current in opposite direction of the current through the solenoid (Lenz's Law). The two antiparallel currents repel each other, and since the solenoid is fixed the can will be crushed.
