Toroidal Motor

[broli]

Regardless of your numberless times of explanation to me, I still have a feeling that a both rotating winding AND magnet in the SAME direction will NOT generate electricity. There is no flux to cross. I believe strongly this is the same as believing that this generator will produce energy just by walking around it when the whole thing is stationary - it appears to be the magnet/coil that is spinning, but the truth is that you are walking around it. See?

When you load the coil (Rotary magnet, stationary coil), it will "drag" the flux in the magnet with it. This drag is a counterforce that will prevent the magnet from spinning. I general, you will allways have Lenz law  acting as long there is energy taken out of the system. If you only measure voltage (No load) there is no Lenz law that counterforce either. You will also have a Lenzless generator if the flux is able to find an alternative path when you load it. However, loading it will result in a massive voltage drop, and left there is literally no energy left to counterforce the system by Lenz law.

You can test this just by moving a magnet around in a toroid transformer. You will measure voltage, but loading it will end up in allmost no voltage, and therefor still no (allmost) counterforce by Lenz law - because the load will force the flux from the magnet to choose an alternative path in the toroids iron core. And when the flux evens out at full load, there is no longer voltage output as you have a perfect counterbalance between two equal but opposite flux crossing the windings.

So according to you a hompolar generator is...not a generator? LOL  . Low-q you are just arguing for the sake of arguing it's a bit stupid. The reason why relative rotation does not inudce a voltage like you just said is because Einstein polluted physics with his relativity theories.The Lorentz transformation which turns a magnetic field into an electric field and vice versa between two moving frames is the biggest bag of bullshit in the whole of "academic" physics. A magnetic field stays a magnetic field regardless of my movement.

I I finally made a big decision. Newton's third law is obeyed all the time. J. Guala-Valverde & R. Achilles's papers and experiments are very obvious now. The reaction force is always the same size as the action force.

Physicist have just been on the wrong road for over a century. There is no such thing as the weak form of newton's third law. All action reaction forces act on the line joining them.

The reason why all the homopolar videos on youtube work is very obvious now. Look at the below attachment for the correct reason why a homopolar motor works with a neo magnet that has a conducting coating. To claim the current going along the conducting nickel is the source of torque is plain stupid because the magnet which is GLUED to this coating has the same but opposite reaction torque thus nullifying rotation. So the source of rotating must be the outside wire like you can see below. If you glued this outside wire to the magnet as well no rotation what so ever will take place. If you allow both this outside wire and magnet to rotate freely you'll see both will rotate in OPPOSITE direction.

These explanations that are popping up on this thread seem silly.  Flame all you want.  Just move your wire so that it's not parallel to the screw or nail - ..come in with it planar to the magnet and your idea falls apart.

In the above picture, nothing has changed from wrong to right.  The fact that they've used a screw only obscures the fact that one can use a nail and achieve the same results.

What creates torque on that particular model pictured is the current flowing perpendicular to the magnetic field created by the magnet.  This is what causes rotation. ...this single vector perpendicular to the magnetic field and radial to the axial rotation.  You could create a spiral copper wire from the inside of the axial rotation to the outside and it would still be this radial vector where the torque force is exerted.  If you were then to create a single path back to the center radially from the outside of this spiral, it would cancel out, equally, the amount of torque generated by the overall direction of the whole spiral.

Rotating a magnet will cause a current to flow in it with from it's center of axial rotation ( given that it's circular ) to it's periphery.  ( A radial path ).  This is natural flow.  Consider that any conductor touching it will induce friction - and then assume that it's not a magnet at all, that it is simply an iron disk - this point of friction with regard to it's axis of rotation is a path where energy is lost ( and moved elsewhere as charge or heat, or both ).  In either case, energy will flow out of the system due to the motion.

As for rotating the magnet with the inductor - ..you're simply adding weight to the inductor, and because the magnet is rotating, a current will also be induced to flow in it if it is part of the path of the current.

Rotating anything in an even magnetic ( regardless of it being a local magnet, or the Earth's magnetic ) field will cause energy (voltage or current ) to flow in it if a path is provided from it's center of rotation to its periphery.  These are just basic Faraday disks. In some cases, the path can be created across the diameter.  ..almost everything which uses disks - whether they're wimhurst machines, bonetti machines, or faraday disks, rely on this principle for operation.

The idea of something being Lentzless ....anything at stationary relative to a stationary magnetic field.  Start changing the magnetic field, then something will  happen in the conductor, start changing the conductor and something will happen in the conductor and the magnetic field.  Both are reactionary.

The reason why homopolar motors work is because the connector is stationary so the half part of the magnet can escape the circular magnetic field in the conductor including the nickel coating.
I cannot see any special thing here Einstein didn't accounted for.
