If I were to use a spiral coil mounted to a board, it should not be able to create any noticeable magnetic drag in opposition to a rotating magnet, since the copper wire will not be able to create much a magnetic field. It has very little induction right? The question now remains, can you induce very much current into a spiral coil winding using rotating magnets?

I hope I'm not WAY off track, lol.

Hi Supermuble and all,

I see exactly what you are picturing in your head. As a matter of fact I've been wondering the same thing many times. You can even image "sweeping" the pancake coil with a N pole from the front and a S pole from the back at the same time.... Don't know if that would improve it further.

The question is: will the motor driving the magnet(s) really see no load? Will making it spin faster increase efficiency of the whole thing to a point where there is more current induced in the pancake coil(s) than the motor consumes?

I have never tried this for the simple reason that it sounds too simple to be true. If this thing would be able to go overunity, someone would have done it long time ago. Or am i wrong?

regards

Ya'll want to know what 'Zero-Point' really is?

Zero-Point is speculating on what something may do when you base your visualizations upon work done by someone else. The thought of no magnetism because there is no inductive reactance AND the coil having little or no inductive reactance without winding one and testing yourself is Zero-Point.

The term 'planar' was used. Since there is no induction then something like a planar transformer is ridiculous, right?

Tell that to a credit card company or most governments. If they believe you then a lot of credit cards and passports should be recalled.

I see three ways to interact with Lenz and his Law:
1. It is there in its full glory, lets not forget all the devices that we use everyday that use this Law.
2. You effectively disable it, and hence take it out of the equation, in ways similar to BEP stated, among others.
3. You sit down and have a talk with Lenz and he decides to help you, thereby reversing his Law just for you because you were so nice to him

I am quite sure, that out of the three, you guys might want to know more about number 3? Or are you thinking it is just a joke?

Let me just give a quick example of how this can be done, and has been done, perhaps unknowingly in many devices, heh.

1. Ok, take a simple low remanence core and wind two coils on it. Call one a power coil, and the other the pickup coil. Both coils should be OPEN.
2. Have a rotor with magnets on it's outer edge. Spin the rotor slightly.
3. Now, what will happen? The nearest magnet on the rotor is going to be highly attracted to the low remanence core material and provide you with essentially free motive power.
4. When that magnet gets at just about TDC to your low remanence core/coils, you fire a pulse into your power coil. This pulse should create a magnetic field that 'zeroes out' the magnetic field from that magnet on the rotor such that the magnet on the rotor doesn't 'see' the low remanence core anymore. Leave the pickup coil OPEN at this time, so there is no Lenz effect from coil to coil.
5. The magnet on the rotor now maintains its momentum and continues around and easily passes TDC. Another thing to remember is, the magnetic field of the rotor magnet is no longer in the low remanence core, it is bend away from the low remanence core because of the pulse from the power coil.
6. So, it is at this moment that the next key thing happens. The power pulse shuts off abrubtly, re-OPEN-ing the power coil. At this same instant, or slightly before, the pickup coil is CLOSED, preferably with a load of some sorts.
7. What happens when that power pulse shuts off? Well, lets look at the situation. We have the rotor's MAGNET moving AWAY from the low remanence core and we have that rotor's magnet's FIELD moving TOWARD the low remanence core. Did you get that? The physical magnet is moving away from the core and WITH MOMENTUM and the magnet's FIELD is moving TOWARD the low remanence core. Remember, the rotor magnet's FIELD was bend and expelled from the low remanence core during the power pulse, so, now that the power pulse is gone, the FIELD is trying to move TOWARD the low remanence core.
8. What happens now? Well Lenz's Law happens! But, this time Lenz helps us. The FIELD enters the low remanence core, and since the pickup coil is CLOSED, Lenz's Law will kick in and the pickup coil will create current flow in the pickup coil and the magnetic field that results from that current flow will OPPOSE the INCOMING FIELD from the rotor's magnet. Did you just see what happened?
9. What happens then is this, the rotor's magnet is moving along with it's built up momentum, and it's field tries to get back into the low remanence core, but Lenz's Law kicks in within the pickup coil and opposes the rotor magnet's field. So, this means that the rotor's magnet will be PUSHED AWAY from the low remanence core BY LENZ'S LAW that is occurring in the pickup coil, this means that the momentum and speed of the rotor and it's magnet WILL INCREASE, and at the same time that is happening, we have POWER FLOWING INTO the pickup coil, all thanks to Lenz's Law.
10. More later, if so desired...

Thanks Lenz...

With proper geometry and design, you CAN have Lenz's Law WORK FOR YOU! It is possible.You might have to 'pay for a single pulse' (and this in many setups might make everything under unity), BUT the fact remains, you CAN make Lenz's Law HELP YOU...

Peace guys...

Hi Tao,

Very interesting idea, thanks for sharing it.

I assume the flyback pulse received across the power coil after the pulse switch-off could also be collected and used for reducing the input power, right?

If you have already thought of what the proper geometry is the most beneficial I would be curious to know (in case  you can share it of course).

Thanks again,
Gyula
