Working Magnetic Motor on you tube??

@CLaNZeR,

Did you try Liquid Wrench Penetrating and Lubricating Oil? It was like night and day--bearings that had no intention of AGW started latching like hell. When I applied it to the rotor at one point it was too good--hindered somewhat the AGW locking. After a while it got back to itself and now latching-wise all is good. To no avail, though. Where is this darn acceleration?

When it "latches" does the rotor decelerate at exactly the same rate as unlatched or does it decelerate at some other value?

Now that's the pivotal question. I don't have the apparatus to study this but I think @CLaNZeR was showing interesting graphs in that respect. He has a tachometer with memory and can plot the rpm as a function of time. That's why I'm waiting with great interest to see his new data  especially in connection with this question.

@Grimer,

Both the stronger and the weaker magnets are at their remanences when left on their own (energy equal to the area enclosed by the respective genuine H-B loop has already been spent to create them as permanent magnets), in absence of external field. That's why they are permanent magnets to begin with.. If they are of low coercivity even weak counter fields can upset them both and get their flux even down to zero.So, it's not obvious that the stronger magnet must always be treated as H when the two magnets are interacting, while the weaker as B. Note, this H we're using to describe this interaction isn't the H that created the permanent magnets. There may be mutual influence and one may arbitrarily choose one to be H and the other to be B and vice versa. Here in this case the magnets are of the same material but their remanences are obviously different but maybe their coercivities are practically the same at that they are not low. Thus, although your theory (requiring the stronger magnet to be always treated as H) doesn't seem to be applicable in general you have to show it applies in this concrete case. This has to be understood first before we proceed.

. Ignore, just realised a  mix up in data, will re-post further down.

Okay quick Wind Down from 500RPM with 3 Stator magnets and no AGW lock attempted.

Original Dampners were standard Aluminium Bar I had hanging around before the 6061-T6 bar arrived.

That's interesting. If you repeat it do you get the same result?

In other words we need to get some idea of the variance within and between groups.

Okay with AGW kicking in approx 320RPM as can been seen by the bump.
