STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

If it never disengages the core, then why is the magnet being attracted to the toroid again ? Sorry but you story is bullshit

Maybe the answer is in the common use of metglas cores

[update]
I had a look at the Alloy 2705M materials they have available.
Below, the B-H curve of that material.
If the H field is reduced to zero after saturation you see no B-field reduction, so no colapsing field.
Fascinating stuff.

This is only true in an increasing current when the flux is not fully engaged inside the core.  At a steady current, the core is saturated equally through out and not partially saturated elsewhere. 
...

The core is never equally saturated because the field due to the permanent magnet has not a toroidal topology.
Thus magnet field strengh and direction depend on the locations in the core, and naturally saturation and permeability also.

In the orbo, it doesn't matter which direction the core is saturated in.  If it did, then reversing the polarity of the pulse would reverse the rotation direction. 
...

Not true. See my other posts. According to the fact that the toroidal coil feels the magnet field due to the irregular permeability along the core, magnet motion induces emf in the coil and Lenz's law applies. Thus reversing the polarity does not change anything:  the current is always in the direction for fighting the flux variation. All is conventional.

Okay guys, let's keep it respectful and concentrate on our build...LOL

So...Based on the information that Paul L. has given, I believe that the best magnets to go with our Metglas MP2510P4AS cores would be either the N25 or N28.  The N25 is rated at 0.98-1.02 T.  Divide this by half and we have 500mT on one end...a perfect match!  The N28 is rated at 1.04-1.08, and gives us about 530mT.  I will be looking for some N25's. 

Cheers,

Bruce

Steorn demonstrates an increase in coil inductance when the magnets are passed by a toroid coil in their Orbo. Steorn then passes magnets past a conventional pulse coil and shows no increase in inductance. The pulse coil in John Bedini's Zero Force motor is positioned laterally, so one of two rotor magnets are at each end of his pulse coil core simultaneously. The position of the pulse coil in Bedini's version would allow for an increase in inductance as the magnets are drawn past manually, unlike the pulse coil tested by Steorn, which has only one side of the coil exposed to the magnets. I would like to see John demonstrate the same kind of rise in his coil inductance in a new video to help prove that the Orbo is nothing more then a copy of his Zero Force concept.

The flux will dissipate inside the core just like it would dissipate in the air if it did leave the core.  When the energy source is cut, the flux doesn't remain and will dissipate quickly.  It doesn't stay around very long when there is no energy source.  If it didn't dissipate after the current is cut, then we could cut the power and still have the flux.  Sorry, but your rebuttal is B.S.
