Negative Hysteresis Engine

[magnetoelastic]

The ultimate downfall of every attempt at a magnet-based OU device is the magnetic hysteresis of any ferromagnetic material used in the magnetic circuit.  Simply put, when any magnetic body goes through a cycle of magnetization and demagnetization, there will be energy lost in the form of heat within the magnetic body.

I would like to direct the reader to a couple of patents, US 5,351,555 and US 6,047,605.  These describe a series of magnetomechanical transducers utilizing the Garshelis Effect.  A shaft of ferromagnetic material is magnetized circumferentially around its axis.  When a torque is applied to the shaft, the helical shear stress creates a helical stress anisotropy within the material, creating a magnetomechanical precession of the orientation of the magnetic vectors within the domains into a helical direction.  Rather than traversing its closed (circumferential) path, the magnetic lines of force are now directed in a net axial direction, emerging from the ends of the shaft, and traversing through the air parallel to the axis of the shaft.

Early implementations of this technology demonstrated typical hysteretic behavior in its mechanical-to-magnetic transduction, characteristic of other magnetic devices.  However, it was soon discovered that if the shaft was constructed of alloy steel, containing at least 5% nickel or chromium, the magnetomechanical transducer would exhibit NEGATIVE hysteresis, with its magnetism INCREASING in strength with each successive mechanical cycle.

The second law of thermodynamics expressly forbids negatively hysteretic phenomena!  Yet it is fairly easy to demonstrate.

I submit this little-known phenomenon to the readers in the hopes that someone may be inspired to create a useful OU device from it.

Interesting that the use of steel alloy causes a negative hysteresis. Would it be possible then to create a magnetic switch, by passing through different material say iron->steel alloy->iron?

Looking for more information on this I came across these.

That seems like something to investigate.  I once saw a viewing of a crashed UFO.  The metal recovered was AL with high levels of iron dispersed throughout it.

Just a thought!
