Hey Bistander,

In a Symmetrical System, Conventional Transformer for example, the Energy Transfer Mechanism is Symmetrical, this means: 1 + -1 = 0, which is Input = Output - Losses = Below Unity

Hi EMJunkie,

Efficiency = (output power) / (input power) * 100%.
Example:
Input power = 100 watts, output power = 95 watts.
Efficiency = 95W / 100W * 100% = 95% .
100W went in and 95W came out as useable power. 5W was lost, wasted, converted to heat or however you want to characterize it, but those 5 watts come from the input power and do not end up in the intended output power. 5W are the losses.
So 100W - 5W = 95W. Input power - losses = output power.
Rewrite the equation like this:
100W = 95W + 5W. Input power = output power + losses.

Straight forward.

Hey Bistander,

Your example is the same, confirming what I said, just with a different equation: Input = Output - Losses = Below Unity is the same as 95W / 100W * 100% = 95% = Below Unity, same thing!

   1: Input power = 100 watts.
   2: Output power = 95 watts.
   3: Losses = 5 watts


100 = (95 + 5) but in Energy Exchanges, the Energy must always be the same, so: 100 = 100 - 5 = 95 Watts, or 95% or Below Unity. You see? You get this way of thinking about it? All Systems have Losses! So again the Input = Output - Losses!

If you run a series of experiments and benchmark a Conventional Transformer, what I said will make more sense.

Hi EMJunkie,
You say:
"Input = Output - Losses"

Using numbers from my example it is:
"100 = 95 - 5"

Using conventional math:
95 - 5 = 90

What am I missing?

Hi Bistander,

No, youre not following the Math.

   1: Input = Output = This says, the Energy Exchange is from the Input to the Output, Output is equal to 100 watts. This an example of an Ideal System, with no losses.
   2: Input = Output - Losses, this says: 100 = 100 - 5, or Input = Output - Losses.


All you need to do is follow the Maths. its self explanatory.

Best wishes, stay safe and well,

Hi EMJunkie,

OK, have it your way. But there are thousands of textbooks and tutorial websites that agree with what I show. Nobody else that I've ever seen, met or heard about does it your way.

Some people get it, some people don't. Sorry if it is too hard for you to understand!

The Output Coil has an Induced E.M.F in it via the Spin Precessional Frequency, or the Larmor Frequency - Yes?
Yes.
Quote
This Induced E.M.F is a result of Faraday's Law of Electromagnetic Induction - Yes?
Yes
Quote
So, this must therefore mean, that Current in the Output Coil will Symmetrically Oppose the Larmor Frequency Precession of the Atoms that are precessing - This is Lenz's Law, Negative of the Source.

Forgive me for correcting you but you have made errors in your statement.  Firstly Lenz’s Law is not an absolute negative, it clearly states that the load current in the output coil creates flux that opposes the change in the applied flux.  That is not an absolute negative, for sine waves it is a 90 degree phase shift.  That 90 degree phase shift of the Lenz flux means that there are regions throughout a full cycle where the Lenz flux opposes the applied flux, and there are regions where the Lenz flux adds to the applied flux.

Secondly within a transformer Lenz’s Law is only part of the mechanism whereby energy is transferred from the source feeding the primary to the load applied to the secondary, or within a mechanically driven generator energy is transferred from the drive shaft to the load.  Your statement “Lenz's Law, Negative of the Source” as an overriding law is incorrect.  If you had said that the power delivered to the load will Symmetrically oppose (apply a load to) the precession motion of the Atoms that are precessing, then I would agree.  But that precession motion is not of our making, it is perpetual and driven by the quantum forces of Nature.  Thus we are no longer talking about a closed system, it is an open system.

A prototype will tell us who is right here wont it. When theory does not cut it, Bench work does!

I thought some people may be interested in my LH Rule for visualizing how the Curl operator applied to the magnetic vector potential A creates the resultant magnetic B field.
