Far as PT Barnum, his quote was " There is a sucker born every minute.". Be surprised that how true that really is. If it looks at all plausible, people will believe it to be true no matter how many times you show them it is not.

There is also a saying that together they go crazy, but each one makes an insight separately. No one can force anyone to be wise or make them happy. The Creator gave everyone the opportunity to make their own choice.

For all those interested and devout believers that EMF on a conductor is induced only when cutting magnetic lines of force. On the slide is the world's first alternator, made by order of Ampere, by the French master of musical instruments Pixie in 1832. In this system, the magnetic flux physically cannot cross the conductor. Second, how is mechanical power P=Fv converted into electrical power W=IU? You see only two questions and a complete discrepancy with the accepted constants of educational physics. In order to organize a change in the constant magnetic flux in a closed conducting circuit, it is not at all necessary to physically rotate a permanent magnet or a permanent electromagnet.

Hello Rakarskiy,

On this design (Pixii Alternator) in order to understand it perfectly well, you need to see it on a 3D Image (Perspective View), not just as you are showing it, because it seems the magnet does not rotate.



So, a better image is above, and it works as follows: When you rotate the handle, the U Shaped Magnet ROTATES while the Steel Core holding the two Coils are stationary (fixed).

Then, it is very obvious that every time the U Magnet turns and switches Single Core-Coil the Magnetic Polarization OR Magnetic Flow Direction reverses, generating AC.
Now, you better than anyone here, that have explained so many times about Electromagnetic Induction Generators, knows that every time the U Magnet rotates, it "CUTS" all those wires that are on its Rotational Trail.
The geometries maybe a bit off (different) related to the later RADIAL or even the AXIAL Conventional type of generator design, based on the Rotation Axis versus the Coils Axis, but eventually it is the SAME thing, different Axis Spatial disposition.

If you "EXPAND" this Pixii Design, say add SIX Coils (instead of just two) every 60 degrees apart on the STATOR, and use for ROTOR, instead of a U-Shaped Single Magnet (Two Poles N/S) but SIX INDIVIDUAL MAGNETS in a configuration of N/S/N/S/N/S or SIX POLES ROTOR...You will end up with a typical Wind Turbine AXIAL type Generator (as a similar one shown on image below, except this one has more magnets and more coils than just six).


It shows in detail how this specific type of generator works on this link>>https://www.mdpi.com/1996-1073/14/24/8509

...it is the about the SAME as the Pixii, but INCREASING the number of Stator Coils as Rotor Magnets....except on this particular design I found, the Steel Core also rotates, as there are many designs, including having double sets of magnets "sandwiched" between coils...or the "core-less type"...

Additional comment: The Commutator added on Pixii original design -on shaft- is just to convert to DC (Direct Currents).

Hello UFO!

I respect your conviction, but you don't accept the obvious at all. To induce EMF in a wirer, provided the conductor is moving in a magnetic field or vice versa, a number of conditions must be fulfilled:

For maximum EMF, the lines of force must be perpendicular to the conductor at an angle of 90 degrees (sin(a) = 90*) along the entire length of the conductor (L). In the area of the conductor, the magnetic induction (Bm) of the magnetic field must have a corresponding value in Tesla, the crossing velocity must be appropriate (v).

E = Bm*L*v*sin(a)

This condition cannot be fulfilled in any way in the Pixie machine. The maximum EMF in the coils of a Pixie generator is recorded when the magnetic flux in the core is fully closed. At this point, the entire magnetic field is concentrated in the body of the magnet and the core. This state is the state of the Anapole Moment (Toroidal Dipole).

Pixie's collector switch was added to his design at the suggestion of Ampere, who was the customer for this device. So in the primary design it was an alternator.

There is another slide where I have given two versions of a generator with a magnetic rotor and a magnet as a core element, both systems work on the same principle of inducing EMF in the coil wires.
