Magnet coil cores, demagnetization power and Lenz delay.

[synchro1]

On the practical side, I wanted to ask Gotoluc to attach a diametric magnet to the back of the ferrite output coil core to measure the effect it had on the output. The thread is currently locked.

@Quote fom JLN:


"In the case of the generators, the increase of the turn rate is produced by the DLE when the devices are loaded above a critical minimum frequency. Below the critical minimum frequency the DLE coil will produce deceleration as per any conventional Lenz generator coil. Coil frequency dictates coil impedance which is a critical factor in producing generator DLE and on-load system acceleration".

Doug Konzen's 8 magnet rotor is traveling at 1405 RPM. 8 X 1405 = 11240 Hertz. He gets acceleration at that rate with a shorted magnet backed ferrite core generator coil:

Gotoluc's most recent DLE experriment used a diametric rotor and a Dremel prime mover traveling at 35,000 R.P.M. 2 X 35,000 = 70,000 Hertz.

Kozen's CMF in Hertz, is at least 6 times lower then Gotoluc's. How much lower would the addition of magnets to Luc's ferrite core make his CMF drop?

How does increasing the magnetic viscosity in the ferrite core effect the magnetic phase lag of the "Lenz Effect" and lower the "critical mínimum frequency"?

It's hard to say what's going on there in Konzens' motor. It could be the basic setup with those PM stacks is causing a drag due to friction and or costy mass de- and accelleration and then the shortened coil just reduces or neutralizes that drag somehow.


It could also be that the shortened coil shows exactly that, DLE. As I described earlier, a coil needs a certain time to get its internal equilibrium (charge seperation evenly distributed) and that may be the frequency mentioned by JLN. The duration of the BEMF spike may be an indicator for the req. frequency.

This scope shot reveals a "magnet wave". Notice how the peaks match TDC of both rotor poles. This is at 30mm down a soft iron core. How would magnets placed at the end of the core away from the rotor effect the distance of the "TDC Wave Peak Conjunction" from the rotor?

There's a time delay for the magnetizem from the rotor to reach the coil. How much time would it take or the "Lenz Field" from the coil to reflect back to the rotor? Would a difference in field strength effect the time delay? Does magnetizem have a constant velocity like light and electricity? The answer is yes!

Officially it's the speed of light, but wouldn't that be weird if the speed is constant, regardless of the medium? All the domains that need to be kicked in iron, compared to rather empty space... Doesn't the speed of sound also vary, depending on the medium?
