The Puzzle Continues - Non Conservative Fields

[lvildos]

there is nothing revealing from this experiment. You can see him loading the system with potential energy at its initial conditions and the rest I see can only be interpreted as the dissipation dynamics. As much as I'd like, a nonconservative field is not evidenced

[AdminOnDuty]

Although each magnet should independently conserve its own interactions, they do not. Instead the primary interaction is conserved throughout the path and conservation is released at a single point for all 8 magnets. This Nonconservative action of handing the primary off to subsequent fields is what this video is demonstrating. Can you think of any uses for cumulative force being released at a single point? ;-)

"Are magnetic forces subject to coriolis effects??"

Google this sentence to see some very interesting papers...

Thanx Rick,

I'll check it out ;-)

Can you do an accurate measurement of the distance between the centre of each of the stator magnets and it's neighbours? See if they form an equilateral triangle, or if it's off a bit? I'd suspect the asymmetry was down to some kind of innacuracy there.

[AdminOnDuty]

Hi ingliss, there are 3 stators;S1,S2&S3. The start point is at S3. S3 is 110.8° from S2 and 110.7° from S1. S2 is 138.5° from S1. S3 is set at 21mm center to center with the rotor magnets, S2 is 20mm and S1 is 19mm. Since the video, I have made the distances exactly the same @22mm and the behavior is the same. AFIK, all the rotor mags are equidistant, I've misplaced my tool for ensuring that, but even so the video shows that a configuration can result in a one way rotor asymmetry for 350°:D

[ingliss]

Hmmm. How about flipping the poles of the magnets on the disc?

If that was done and the direction of asymmetric behaviour you observe is then reversed, would't that eliminate the possibility of some sort of mechanical inaccuracy or bias?

pretty cool! nice work!

Nice demo of some of the asymmetry.

Thanks,
