Does Lenz' law apply to a conventional homopolar generator?

[leeanderthal]

In a conventional homopolar generator (not an N Machine) I believe that the magnetic field is uniform. If so, then the flux would only change during acceleration and deceleration of the disk.  While the disk is spinning at constant speed the flux would be unchanging.
If Lenz's law states that "the magnetic field of any induced current opposes the change that induces it" and there is no change, then is there an opposing force? Other than windage, mechanical drag and eddy currents.

Hi Lee
I know nothing about HPG's but if there is no change in the flux,there will be no lenz drag,and unfortunately no juice either.

That's whats puzzling me.  It is obvious that in a conventional generator where there are a plurality of poles, flux is constantly changing.  But an HPG is acyclical.  I seems to me that the flux is uniform and unchanging, yet there is "juice".  So, either I am wrong about the flux or Mr. Lenz is wrong about the drag. ;-)

Hi Lee
As I said I no nothing about HP G's,and very little about anything else!!
I never seen any gen.that is landless,and believe me I've looked and experimented.
Not to say there aren't any.

Sorry Lee
I'm sure you knew, not landless, lenzless
