fun observations about the magnetic field

@TinselKoala,

What do you make of this?

Quote from Dr. Stiffler:

"Just wanted to show this short video on how field arrangements of permanent magnets can be so arranged to obtain motion with no external energy input".

I think that's 7 minutes and 41 seconds of my life that I'll never get back.

The pendulum slows down over the time of the video. The pendulum also couples EXTERNAL ENERGY INPUT in the form of vibrations into the pendulum motion. Stiffler knows that it is very difficult to isolate such a system from external vibrations, air drafts and the rest of the possible sources of _external energy input_ and he has done none of that for this demonstration. In short, Yet Another very misleading demonstration of an ordinary phenomenon from Dr. Stiffler.

From the clip:

When the lens is placed in a vertical position (perpendicular to the Earth's surface), the magnet rotates counterclockwise in The upper side of the lens and clockwise in the lowe side.

It has nothing to do with upper vs. lower.  It's just a question of left-to-right movement and right-to-left movement.   The rotation of the magnet is consistent with respect to the change in the direction of movement.

@TinselKoala,

I built a perpetual set of moving magnet wheels from plans of a modified "Bessler Wheel". You can try it and you have my solemn word of honor that it will never stop. I sandwiched upright ceramic block magnets between six plastic cake serving dishes to form "Three Wheels". Two identical wheels of 8" diameter with 8 magnets apiece and one 16" center Wheel with 16 magnets. All the magnets are in opposition, except 3, one on each Wheel in attraction. They balance upright on bearings and the three wheels share 8 possible rotation sequences. A partial lock position will appear, but not for long, as an oscillation begins and breaks finally with explosive force. I had my three wheels positioned in hat boxes with 4 Windows cut, 2 on each end of the 16" center, for the magnets to pass and influence one another. Never stopped moving, so help me!

Jerry Bayles presents a quantum theory of "Magnet Chirality" that explains why mirrored magnets cannot share equal strength. Imagine the sole attraction magnet on one 8" side Wheel locked "between" two magnets of opposing polarity on the larger 16" center Wheel. The 3 magnets then begin to do work on the quantum plane, exchanging forces, untill an imbalance appears as Jerry explains, imparting new momentum to the wheel works!

What part of "couples external energy input" are you having trouble understanding? I assure you that if you successfully isolate your device from all sources of external energy, like specifically vibrations, it will come to a stop. I have no doubt that if it is just sitting on a table top that it will keep on moving. I've seen a torsion pendulum that was so sensitive that it "kept moving" perpetually... because every week somebody parked an 18-wheeler about 50 yards away outside the building and the thing was actually _gravitationally attracted_ to the mass of the truck, and this was enough to keep it swinging. The business of eliminating all outside sources of energy is not a trivial one.

As far as the lens thing goes, I covered this topic some months ago. The curvature of the lens causes the magnet to contact it at a single point (roughly). But the "pull" from the other magnet acts through a different point. So a force couple is produced: the frictional force at the point of contact dragging back, and the pull force off-center to this point of contact. Hence the thing rotates. The direction of rotation is predicted by the geometry of the force couple. It's simple dynamics and would work the same way if you were able to pull offcenter with a string. Of course pulling with a magnet allows free rotation about the point of contact , whereas a string wouldn't.
