The herringbone gear works well as an analogy but we must remember the gear turns independent of the shaft.
In this way we can understand how the fields are asymmetric but still work together.Half of the Answer is knowing the right Question

Another interesting thought using the gears, when we stack them inside each other they share a common shaft.
Just a thought exercise
If we have three gears, one inside the other, 3 volts on two outer gears and pulse the inside gear very hard and fast we should be able to accelerate the two outer gears more than a normal 3 volts would rotate them. Or maybe accelerate the #2 gear which in turn would drive the inside gear faster and in a cw direction, the outside gear slower but with more torque in a ccw direction.
I'll ponder on this awhile
We should be able to see a geometric position that would enable us to use the fields like leverage, using a large one to accelerate a small one.
We cant turn the shaft but we can accelerate the gears using electricity.Last edited by Dave45; 10-05-2012, 11:48 AM.Half of the Answer is knowing the right Question

Lets stay with the gear analogy for a bit.
Now we'r still looking at the gears one inside the other here.
The problem is bemf, when we pulse a gear it moves forward with high speed but when the pulse ends the gear tends to reverse, therefore opposing the other gears and any increase we had. Its like spinning a flywheel but right before you let go you pull it back, killing any acceleration you had.
So how do we position the gears so the bemf doesnt effect the other gears.
Lets look at what happens to our gear as we pulse it, it not only comes back but it also comes apart, it dissipates.

The true force is centripetal but the rebound force is centrifugal, if we spin a magnet on its axis a very high speeds we get a centrifugal force that would resemble our galaxy.
Our galaxy has an equatorial plane, using the asymmetric model we can see why, as the herringbone gear spins at high velocity the centrifugal force caused by inertia would form and equatorial plane a split in the center because its asymmetric.

As our gear comes apart in our circuit we see one side as femf and the other as bemf.
And it fits the inductor model reaction, the forward emf moves on into the load keeping the bulb lite after the switch has been disconnected and the bemf runs counter to the applied current.Half of the Answer is knowing the right Question

Its a paradox for sure
Say the two outer coils are powered with a steady 5 volts and we want to add to them with a center coil, as you can see the center coils magnetic field opposes both outer coils, will this impede the system or make it snap back faster

Using the herringbone gear has helped me understand, I think
This is what I think happens when we pulse a coil the fields actually cut the inductor
When the pulse is on it cuts the inductor but when off the connection is broken and we get a reverse direction in the fields a snapping back action,at the present we catch the field snapping back \\\\\\\\\\\//////////// or by spinning the magnets and stealing their field with a conductor but
Can we catch the field as it moves in boy do I have some idea's on that one.
Can we iceolate that field
