Delayed Lenz or not?... post your explaination!

   Tinman,
             I'd think speed of magnetic field in a vacuum and speed of light would be about the
same. I've often wondered about the sun and Curie temperatures and how that works.

The Dremel is connected to a Kill-Watt power meter at all time to verify its power consumption.
The power meter has zero change when the coil is connected to the 1 and 12.5 Ohm load. There may be a half Watt increase (hard to tell) when the coil is connected to the 25 Ohm load but it's delivering 3.2 Watts. 
So the coil connected to the 25 Ohm load delivers 2.7 Watts output at no power cost to the prime mover.
and the coil connected to the 12.5 Ohm load delivers 2 Watts output at no power cost to the prime mover.

This is what I'm interested in and I think others should also be.
Keep in mind my test device is a toy at best but it's enough to demonstrate a value and I think it warrants more study.
I've said and tested this in the past that a larger scale device will produce much more power with the same benefits.

Sorry Luc, but you are leading yourself down a garden path.  You know there is Lenz drag and you know the motor has to put out power to overcome that Lenz drag.  The Kill-a-Watt meter is not designed to detect small changes in power.  It's a device to use in the home to measure the power draw of appliances and other things like TVs, etc.

If you can mount the same magnet on a small 5-volt or 12-volt DC motor then you can easily prove this to yourself.  I assume that you still have the big low-pass filter device that Poynt99 helped you make.  I also assume that you have your fancy volt meter with six digits of precision after the decimal point.  All that you have do is connect your battery or power supply to the motor with your low-pass filter device in between.  Then connect your fancy volt meter across the current sensing resistor in your low-pass filter device and you will see the current draw by the small DC motor increase when the generator coil is driving a load resistor as clear as a bell.

I may try to look at the Naudin tests later.  However, I have mentioned in the past that I am not too impressed by him.

Tinman:

I will let you look that up.  Try searching on "speed of propagation of a magnetic field" or "electromagnetics 101" or something like that.  The speed of EM waves is determined by the impedance of the medium based on the permeability and permittivity.  I am assuming the same applies to a "DC" magnetic field.  The subject matter of the speed of propagation of DC electric and magnetic fields does not crop up too much but I am sure you will find it somewhere.

Hi All, When you energize a coreless drive coil that is pushing a permanent magnetic rotor, Does Lenz show up at the exact time as power on or does it manifest a few micro-seconds afterwards?  I think it is the latter.
When you pass a magnet past a coreless gen coil that is loaded , Does lenz happen simutainously or does it lag?
I think it lags but not by much , you have to switch at just the right time.

I can assure you that JLN is even more un-impressed by you!
