Confirming the Delayed Lenz Effect

[gyulasun]

...
BTW ITS NOT DELAYED LENZ BUT "SHIFTED LENZ" AND WHY TESLA INVENTED BI-FILAR WINDINGS TO GET RID OF THE EXTERNAL CAPACITORS.

Hi Thane,

My understanding on Tesla patent on Coil for electromagnets
http://www.tfcbooks.com/patents/coil.htm is that he neutralized the coil's inductance with the capacitance attained between the bifilar wires so that the input current found resistance only that of the coil's DC resistance. Does not this mean resonance and if it does then it could not give 90° phase shift but zero degree only?
Quote: "I have found that in every coil there exists a certain relation between its self-induction and capacity that permits, a current of given frequency and potential to pass through it with no other opposition than that of ohmic resistance, or, in other words, as though it possessed no self-induction". Unquote

So he did get rid of the external capacitors with using the  'distributed capacitance of parallel wires but then he must have got a phase shift of near or at zero degree.

Great news gotoluc! In the back of my mind I knew it was possible.
For those of you interested in building a cheap, pure sine wave inverter, here is a nice pdf:

At everyone,

I connected the circuit to my H-Bridge but used 12vdc first so not to blow things up. The results are not the same then with the grid 120vac 60Hz sine wave.

There could be a mistake somewhere so lets look at this over carefully. Maybe the power meter I'm using is being fooled in this kind of configuration?

A youtube user posted this: "Sorry Luc, but I have to correct you on the voltage leading the current. In a capacitive circuit the current leads the voltage. This is what your scope is showing. Scope traces go from left to right with time."

I thought it was the other way around?... but I may not have it correct. Can you look over the scope shot below and comment.

I think a pure sine wave output inverter would help confirm but I don't have one. Only modified sine wave I have. I'll give that a try and let you know.

Thanks for sharing

Hi Luc,

Great Video...

Wattmeters base their reading on: E * I * cos(phi) or (power factor).

I am curious if your power meter is capable of showing the power factor. My power meter can show this value, and it shows me also if the load is running inductive or if it is running capacitive. I think that displaying that (those three individual values: E * I * cos(phi)) will help you a-lot.

With Kind Regards, Overunityguide

I bought this for arduino to make DIY signal generator:

But I don't know how to amplify the signal to get something in the range 20V 3A AC. Probably something like powerful audio amplifier?

Look around in some recycle electronics shops or even pawn shops for a pre 1980,s analogue amplifier. Old record players are a good source for dual channel analogue amps.

Digital amps for this type of experimenting are not really a good choice as many of them employ a direct coupled output, with a DC offset bias, which will affect your primary winding current consumption in a negative way. This is rare with analogue amps.

Besides that, old analogue amps are usually dirt cheap.

Cheers.
