Solid State Generator via Electromagnets + Halbach Array

[void109]

Just had a notion, and tried out the model in a magnetostatic simulator.  With a Halbach array you end up with one side of the magnetic configuration having roughly twice the magnetic field it would have without the configuration, and other other side is roughly nil.

If you have a Halback configuration of Up, Right, Down, Left, Up - all of the flux is to one side.

Replace the second and fourth magnets, Right and Left with solonoid type electromagnets that we'll pulse with AC current to act as a transformer.

When the second and fourth magnets, shift from Right Left, to Left Right polarity, the entire field shifts to the other side.  So we can pick up the current from the magnetic fields we are creating, and also the fields of the other three magnets as they are shuffling back and forth within the halbach configuration.

It seems obvious so its probably an old idea thats been hashed apart somewhere already.  I just havent seen it.

Hi Void109,

That is a really good idea. I drew a version where the coil gets placed along the magnetic field lines. It may be better to have the input coil 90 degrees to the pickup(?). If this is all wrong let me know I'll redraw it.

Was thinking something like this:

Sorry about the monster image size, I'm a completely new scrub to making gifs - that's my first, not sure how to resize it yet.

Always wondered why noone had tried something like this? I had a design something similar to this, but mechanical. The idea was to rotate the outer and and center magnets in the array in unison and to wrap flat spiral coils around the other two to capitalize on the flux change.  Never thought about using electromagnets though, good idea, much easier to impliment.
