Hi Thane
Removing the magnets are a problem as they got glued  to the holders with jb weld however i went back and repeaded
the test with the magnets setting on the shaft 5 times same results throw switch acceleration open switch deacceleration.Doing video 4 is a bit too much for right  now, i have also put 8 neo magnets on the coil core back part the result is increase cogging or decrease cogging,the  acceleration effect still works. in video 1,2 did you ever put a non magnetic material in place of the magnetic one across the air gap such as a  copper rod or a  brass rod.It seems to me that your dealing with lenzs law and something unknown created at the same time
and effects of lenzs law and the other do not run the same that is bigger coil ,more magnets more lenzs effect but not as much other effect,Its not a one to one example.I get very little lenz effect but big acceleration effect,also my coil is much fewer windings than the coil in video 1,2. and I use 2 magnets per holder.

Can you upload a photo or even a diagram of your setup?

ok heres a pix,the magnets are still on the shaft,i had trouble up loading a pix before.

YOU ALSO HAVE MOTOR ROTOR FLUX EXITING AT BOTH ENDS OF THE DRIVE SHAFT - AND WHERE YOUR ROTOR IS CONNECTED - SO THERE MIGHT BE SOME MOTOR ACTION AT THE COIL AS WELL.

RE: NON MAGNETIC MATERIAL...
THE BRASS COUPLER IS NON MAGNETIC RIGHT?

NO YOU ARE RIGHT LENZ EFFECT AND ACCELERATION ARE NOT EQUAL BECAUSE LENZ EFFECT - COIL BACK EMF INDUCED FIELDS ENTER THE HIGH RELUCTANCE AIR GAP WHEREAS
THE MAGNETICALLY COUPLED WAY IT IS ATTRACTED TO THE STEEL SHAFT THROUGH THE AIR GAP WHICH REPRESENTS A LOWER RELUCTANCE SCENARIO.

Wrong.
The coil can not tell you the strength of the field inside (unless you monitor it from a known zero flux level), it can only give you details in the rate of change.
if you have a 100,000 gauss field and it drops 1 gauss to 99,999 gauss you get the same voltage (and current) induced in a coil of wire around it as you would for 1 gauss dropping to 0.

Aether, sorry but you are wrong. The coil will indeed provide a measure of the field strength inside. Your example is false because this is not a step-function change we're talking about: it's an alternating field. An alternating field will induce a current in the coil that is proportional to the magnitude of the field, since for an alternating field its rate of change is proportional to its magnitude.
