GAMMAMET cores: incredible efficient cores.

I happened to stumble on this particular website by accident:

And my first reaction was  . That core is incredible efficient and is suited for high currents. This has many implications and uses, especially in the OU field. Most of the times OU effects are measured in mW due to low powers needed to saturate a core but this would allow them to scale up to the 100's W range.

Isn't this similar to Metglas?  They also use nanocrystalline type cores and very high permeability materials.  Metglas is what Beardon used for the MEG.

This is not similar to Metglas.  Compare the hysteresis loop of Metglas to the Gammamet hystersis loop and you will see the difference.  Gammamet has a near 0 hystersis loss and returns to a near virginal state, while Metglas has a significant core loss, relatively speaking.  Gammamet has a low remenance, and Metglas has a high remenance.  Also, Metglas has an extremely high permeability which will saturate at very low power, while the Gammamet has a low permeability and will require more power to saturate it.  I would rather have an OU effect that is 100's of watts instead of mW's.

Thanks for bringing this to our attention Broli.  This is an excellent find.  Gammamet has a really beautiful hysteresis loop and is nearly perfect.

Thanks for explaining that.  I didn't have time to dig into it but just noted that they sounded similar at first glance.  This sounds like a very important find.

Like I've been saying for about 3 years...

Ferromagnetic Substances are a great candidate for OU devices.

Thankyou Gavity Block !!!

I believe few here understand

     1. Magnetic Permeability.
     2. Magnetic Coercivity and it's relation to a hysteresis loop.
     3. What Anisotropic Energy might be and it's relation to Bedini/ Joule Thief Spikes.

When you take something that amplifies the Magnetic Field of a Coil by 1 Million times
                                                                                           (and let it crash by turning OFF the energy) --> you might have something !

Sounds like this Gammamet would be a great material for our goal here.
