Modulating magnetic field with a Graphene or Pyrolytic Graphite

[tarakan]

Hello

How much energy would be required to rotate a disk that would interrupt a magnetic field of a permanent magnet and prevent it from reaching into a coil?

This system can be designed so energy required to"cut" the diamagnetic into the magnetic flux will be compensated by the energy of pushing out the diamagnetic on the other end.

Would it be possible to mechanically shield flux with a diamagnetic at a correct frequency and cause an Inductor Capacitor circuit to oscillate?
(Induction would be the pickup coil and the mechanical shielding will happen between the inductor and the permanent magnet)

I read that graphene can change its diamagnetic properties if a small voltage potential is applied to it.
Does it mean that it can be used to modulate a permanent magnetic field and to create overunity energy?

If I design this device so all shied repulsion forces are canceled out by shield repulsion forces in a different direction, than what will prevent this system from achieving overunity?


Did anybody ever play with graphene and its ability to modulate magnetic field, when electricity is applied to it?

=============================================================================================================

I glued a coil and a permanent magnet to a copper black plate.
There was a small gap between them.
I took a small square of a pyrolytic graphite that I had and slid it in and out of the gap.

The change of voltage across the coil was barely observable on the lowest setting of the oscilloscope. It was 0.0000001 volt or something like this.
I am too broke right now to experiment in this direction.

But is it possible to make this effect more noticeable, while keeping energy losses to a minimum?


How can graphene's ability to shit off magnetic field when voltage is aplied be used in hobby overunity projects?
