Magnet coil cores, demagnetization power and Lenz delay.

Ah, I see...never mind.  It is entirely possible that it was I that misunderstood you.  Ceramic bearings are great, and there are, of course, various grades.  I have found that the ones sold for skate boards and roller blades are actually pretty good and about 1/3 of the price you mentioned.  If yours is a higher precision than, that would make sense.

@Pirate88179,

The problem with the cheaper ones is that the ceramic ball bearings are set in stainless steel casings and all the stainless steel is unfortunatly magnetic. I just recieved two messages from manufacturers today confirming this. I believe that the presence of this material close to the magnet rotor will create drag and eddy currents and slow the rotor down. Lidmotor uses them at the ends of an extended axle with a high degree of satisfaction, but for internal magnet bearings I'm certain that the "All Ceramics" are far superior.

Here's the answer I got for the one pictured below:

A seller answered your question, "is the stainless steel non-magnetic?" about 1/8 x 1/4" Flanged Ceramic Miniature Ball....

@Pirate88179,

A carbon fiber axle would help mitigate the effects of the magnetic stainless Steel. The advantage is that they would stick to the sides of the magnet. I think they're worth a try for the Price. There'd still be a homopolar vortex generated, but who knows how much it would hurt?

Here's a set of 4 from Amazon like the one pictured above for $35.03 plus free shipping!

OK, maybe I can help with this as we were in on the design and creation of ceramic bearings long ago.  All, not most, but ALL of the benefits of making/using a "ceramic" bearing go to hell if you use a metal race.  Not just for your experiments, but, think about this....-you have this very hard material and it is very wear resistant and chemical resistant, and you surround the contact for this material using a much softer material......what you have is crap!

In other words...(I also worked on this project for GM)  you have piston rings made from ceramic which is good for wear...BUT, the mating surface of your cylinders is aluminum...(or even steel) ok, do the math.  No benefits at all, and....even faster wear.

Who the hell makes bearings like this?  The ones I looked at from skateboards "looked" like total ceramic, but...I have never purchased any and if they involve steel then...it is crap.

Here's a DPDT schematic and picture of a blade switch: #1 connects directly to #2. #3 connects to the positive terminal of the battery and #4 to the start wire of the bifilar. #5 connects to the positve side of the Reed switch and #6 the negative side of the Reed switch. The end wire of the bifilar connects to the negative pole of the battery.

Once the blade switch shorts the coil directly to the battery, the coil turns into a D.C. electro-magnet. Current draw becomes limited after that by the standard formula of voltage divided by resistance, I=V/R. Any rotor acceleration followed by the direct connection would necessarily defy the second law of thermodynamics, and would serve as unconditional proof of an overunity circumstance.

This test, if successful, would catagorically confirm "Lenz Reversal" as an overunity effect once and for all and not a "Zero Sum" mechanism as our "Cynics" falsely maintain.
