Magnetic wheel by steel shielding

By moving a steel plate as a shield between two repelling stack of magnets, one on wheel and another fixed to the table, the
wheel can be made to rotate continuously.
If a roller ball is used between the magnet and the shield, the shield can be moved easily over the surface of magnet because the magnetic field is almost uniform in parallel plane.

The iron plate experience a magnetic field that is stronger when you position the rotor magnet side by side to the stator magnet. This will resist the iron sheet to be removed, so you need energy to remove the plate.
If you installed a lever on the rotor that rised the plate automatically, the motor will stop.

I've pretty much given up on most OU stuff. My pendulum that goes from 2pm to 6 to 9 to noon
without getting stuck at noon gets totally ignored. And likewise my permanent magnet slider.
Some people do not recognize overunity   when it knocks them over the head.

I do have some hope for the Kerry Waenga Bessler wheel. I have made 1 of 5 segments and it
does what is claims to do. I need to add 4 more to see if it rotates. Many times what one segment does will not apply to a full wheel.  It uses gravity to store
potential work in a spring which is then used to kick the weight forward and upward over 8 degrees.

You may want to watch that on Bessler.com.

Does this material block magnetic flux without getting attracted to magnet?  Is it real or fake?

Hi Vineet,

It is real, I mean it is able to block magnetic flux but it does have magnetic permeability of around 80,000 so magnets surely attract it excellently.

Some more info is here: https://www.3m.com/3M/en_US/company-us/all-3m-products/~/3M-Flux-Field-Directional-Materials-EM80KM/?N=5002385+3289539403&rt=rud   or here:https://www.digikey.com/en/product-highlight/3/3m/flux-field-directional-materials-for-nfc-rfid-and-wireless-power-applications     

All such magnetic flux shielding materials, made for supressing or attenuating unwanted EMI / EMC issues have magnetic permeability.

Thanks for the reply and link.  Interesting here is that  such a thin plate can absorb so much of flux.  If a strip of that material is used as a leaf spring so that the force of attraction from magnet is neutralized  by bending of the spring,  can we make a 'forceless' shield?
