Magnet motor theories

[Smudge]

Smudge, do you think multiferroics such as Iron Oxide or Copper oxide might have this kind of capacity for "clawing back" some of the to-and fro movement of magnetic fields?  Here's an interesting presentation among the growing number on YouTube:

Bob,

I do indeed think that multiferroics have that capacity.  In particular the ability for an electic field to change the magnetic polarization, so maybe not the actual compound being studied in that video where a magnetic field changes the electric polarization.  It is possible to obtain multiferroic effects using layers of different materials where the effects occur on the surface.  If you google "magnetoelectric effect" you should find some references where this effect is being investigated as a means for electric field control of magnetization with the aim of magnetic storage of digital data at lower power cost than at present.  The individual layers of material are not necessarily multiferroic, thus you can have a ferromagnetic layer in contact with a ferroelectic layer.  Of course the research is looking at tiny magnetic structures where the layers are very thin, but the basic surface phenomenon can apply to larger bulk materials.  As I said before, if you can go round a BH loop without inputting the energy related to the area of that loop, that is a tacit assumption of OU.

You can extract energy from a ferromagnet very easily in the form of magnetic-field energy.  If the ferromagnet is supplying field B₁ you simply supply another field B₂ from a coil wound around the magnet and the resulting field is B₁+B₂.  The field energy is proportional to B² so you end up with B₁²+B₂²+2B₁B₂.  The first term is the initial energy supplied by the magnet, the second term is the energy supplied by the coil and the third term is the anomalous energy supplied by the electron spins in the magnet.  If you don't believe this just replace the magnet with its coil equivalent and analyse it.  Aspden thought he could capture some of this anomalous energy with his reluctance motor, but his analysis wasn't complete, he ignored the energy associated with the field within the magnet.  The simple reluctance motor doesn't work, any energy gained is clawed back when you return to starting conditions at the end of each cycle.

But if you can switch a ferromagnet on and off, or better still reverse its magnetization, not via applied magnetic fields but via electric fields, the claw back problem might disappear.  That is certainly worth exploring.

George Bugh sent me one of his books.  A lot of thought went into his research.

TS,

I too have studied inertia, in particular as applied to gyroscopes.  I saw Laithwaites Royal Society lecture on TV, attended another of his lectures in person and corresponded with him.  I even attempted to build a thrust motor using gyroscopic principles.  And being an electromagnetic engineer I studied inertia and gravity from that background.  I have similar views to George Bugh and firmly believe that gravity, inertia and electromagnetism are all linked by a common cause.  Perhaps one day I will publish my views.  The common theme is that so called empty space is not empty at all but permeated by particles having zero rest mass but also having spin, not unlike neutrinos.  These travel through our space at light velocity c and, although being massless, they do exhibit momentum p and energy p*c.  Matter particles absorb and emit these space particles, hence absorb and lose momentum.  The time delay between absorption and emission accounts for mass inertia.  The direction in which the emission takes place is determined by the spin of the absorbed particle, hence this can be offset from the arrival direction and this accounts for electromagnetic effects.  I see all thermal motion and all sub-atomic motion such as orbital, precession and perhaps even spin of matter as being driven by these space particle interactions.  And that in my mind is an enormous source of energy if only we could discover how to tap into it.

Bob,

Just looked at the Stubblefield situation.  I don't think his earth battery used the earth's magnetic field nor did it use "magnetic current" as some people believe.  I think the answer may be more simple than that.  Basically the thing is just a battery using Fe and Cu as electrodes and (earth contaminated) water as the electrolyte.  But the electrodes have a special geometry in that they are spirally wound coils.  Now if I am right the performance of the battery would improve if the electrons flowing from one electrode to the other, instead of arriving normal to the surface of the electrode, actually arrived at an angle, and that angle is in a direction to support the current flow along the wire.  With adjacent Fe and Cu wires wound in a solenoidal bifilar manner, the presence of a magnetic field that is parallel to the axis of the solenoid will cause the electron trajectories across the gaps to bend so as to create that angle of approach (this is classical cyclotron curvature).  That magnetic field is created by the load current flowing within the electrode coils and also within the secondary coil, if the polarity of the connections is appropriately arranged.  The Fe core enhances that magnetic field for a given load current (hence the reason Subblefield used a long solenoid).   This magnetic enhancement creates positive feedback and increases the activity of the electrolytic cell the more you load it.  That theory fits well with the reported power being much greater than would be expected from electrolytic action alone.  And if I am right it opens the door to enormous improvements in cell technology by the use of spiral electrodes and permanent magnets.

Smudge,
Thanks very much for taking the time to reply to my queries. I've been travelling today for work, but will take some time to digest them over the weekend, and respond.
