Magnetic/Electromagnetic Diode

[elias]

Hi,

I thought to throw this thought over here, maybe something useful grows out of it.

Here is a link that describes a new type of diode called "electromagnetic diode" which enables EM waves travel only in one direction through it: Physicists Build Diode for Electromagnetic Waves - Technology Review

Now consider another type of diode, which I don't know that we have built yet: a magnetic diode.

The magnetic diode only allow flux in one direction and not the other way around. If such a device does exist, the Lenz law is clearly of no concern any more. Why?

Because if you put the magnetic diode in front of the core of your coil then, you'll see that the coil cannot affect the rotating rotor in any way, because the diode will block the flux to the rotor, and will also allow flux from the magnets to penetrate the core. That's it.

I'm not sure that would apply the same way. Wouldn't you want the flux to saturate the core then collapse? The change in flux is what causes current to flow in the wire. It's not the flux that is the problem it is the current in the coils that creates the reverse field or Lenz effect. Blocking the current in the coil on entry (one direction) and only collecting the collapse might have a more significant effect. Interesting line of thought though - what else could a flux diode be used for?

Elias;
once you control the magnetic flux efficiently you win.
The flux is difficult to beat as you know.
I thought Butche Lafonte was making progress with magnets but have'nt heard much lately.

on the EM diode:

Ilya V. Shadrivov uses polarization change in an artificial chiral metamolecule such as lithium iodate in a non-linear mode.

Dragon; computer memory such as mem diode or on a large scale a warp drive. ((di-lithium crystals) sorry)

Yes you want the current to flow this is inevitable, but if your cores could block the flux generated by the current, then it would not hinder the rotation of the rotor.

I always figured you could make a Tesla 'valvular conduit' analog for a magnetic field Tesla Patent 1,329,559 - Valvular Conduit.... take that concept and wrap it in a loop to apply to a toroid too

Butch has been very active over the last month with new designs at overunity.com.

I am not quite sure, about what that is, but you made me think of using ferro-fuilds in a cylinder as coil cores. When the magnet approaches the fluid, it draws the magnetic particles near the magnets, and when the coil reacts as Lenz indicates, the ferro-particles will move away from the magnet, without causing much reaction to the rotor.
