Lorentz "Extracted" completely from All Maxwell Work the word "coil"...to replace it by a "single wire", first a "straight wire" and then loop the single wire inside a static magnetic field to understand "how a motor or generator works".

The difference between coil and single wire analysis resumes in only ONE thing...a Secondary Magnetic Field existence.

A single wire would never generate a second Field within another Field, actually it is just a drastic SHORT CIRCUIT...which will NOT DO ABSOLUTELY ANYTHING, except throw a lot of smoke, heat and melt under a current circulation.

I can only relate Lorentz single wire loop example as a resistance for an electrical cook stove (not the induction one, but the old type that consumes hundreds of Kilowatts per minute, and that gets melting red hot)

Now, with a Coil, EVERYTHING CHANGES, because we are adding Resistance, Inductance and many other parameters...

BUT besides all parameters, a coil generates a SPATIAL MAGNETIC FIELD.

Now, this Field is Spatially originated within that loop of wires called COIL, BUT, it EXPANDS into a Spatial Volume beyond the coil limits.

So, in reality, when we replace the single wire loop by a Coil on the same image that I have shown before, then we have this result below:


As you all can see, the difference is huge!!

But mainly, a SECONDARY FIELD has originated within the Primary Field, as soon as we run a current through the coil.

Now, because of the positioning of Both Fields ARE NOT in a Magnetic Chain Alignment of N/S-N/S-N/S, or as I call it: "At Magnetic Equilibrium State", this coil would tend to SEEK EXACTLY that positioning...

This tendency of the Secondary Field to seek for an alignment, generates Four Forces within the Air-Gap Space between them.

Two are Repulsion Forces (Fr1 & Fr2), as other two are Attraction Forces (Fa1 & Fa2)..BUT, more importantly, all these Four Forces are NOT Perpendicular to the Coil Loop nor the B-Field like Lorentz states on his Law!!!

These Forces are ANGULAR TO THE SPATIAL INNER FIELD, generating a TORSION EFFECT.

Note: This exactly 'Scenario' applies as well to a DC Brushed Generator or a "Dynamo".

To be continued...

Ufopolitics,

Don't get too hung-up on the "single wire" - it's probably used in the explainations
to simplify things.

Your explaination tends to focus on a single wire (may be misleading at first glance):

Consider "Current Density [J]" - the amount of charge per unit time that flows through
a unit area of chosen "Cross Section" - a vector whose magnitude is the electric
current per cross-section area at a given point in space.

Measured in amperes per square meter - a single wire of cross section "A" or a bunch
of wires with cross section "A" in m².

SL

Formulas - Circuit (wire) moves and Field (magnetic) changes.

Examing the two equations in analytical form (formulas) might
help as well in "seeing the differences."

Which form might not lend itself to "Lenz?"

Attached: "flux rule"

SL,

I believe you are the one who is getting hung on the single wire, single charge, single magnetic field.

The main point here is that a "single wire loop" does not project a Spatial Secondary Field.

And it is not just "to simplify things"...otherwise it would give us the first and second laws (for single and multiple strands)

However, this is easy to reconcile (find/settle) on Ampere-Maxwell Laws, as also on Gauss Law for Magnetism:




If we go to ALL the Lorentz Mathematical Equations about his Force Law, you will NOT find a single one that have a "Secondary" B-Field (magnetic field) ...it is all about ONE B-FIELD, ONE E-FIELD.

It is obvious that the single wire, having a moving (q)charge within a B-Field will manifest a Force F the way he states.

However, everything changes when we apply Ampere, Gauss and Maxwell Laws (see image again, above.) many conductors, having ALL the same circular current flow, GENERATES A FIELD, another B-Field, a Second Magnetic Field.

So, please provide on any Lorentz Force Formulas that you can find out there, where is this Second B-Field ?? configured by the loop of the single wire or several turns of wire (supposing 'single wire loop' is completely "hypothetical") within the Static Magnetic Field which is the ONLY ONE denoted as B...and of course, running a current on wire(s) denoted by charge 'q'.

I will be waiting...

When wire moves?...the Static Field changes?...that's wrong.
What is stated on Lorentz Law is that either the E-Field (Static) or the B-Field (Dynamic) can be ruling the equation as being 'active'
No wire on the single wire crossing the B-Field moves, 'wire moves' just on the Motor-Generator application of the law as I have stated before.

On the Lorentz formulas there is just one electric field (E), just one magnetic field (B), a charged particle (q) and a velocity (v)
And that's it.
Then review Faraday and Maxwell Formulas...they include variation of Flux, over variation of Time...

Have I even mentioned "Lenz" here?

I do not think so.

Lenz Law have nothing to do here, except noise and confusion.
