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

I'm currently setting up a presentation on this subject diverting a bit from the real orbo. Basically when the permanent magnet is close to the core the dipoles of the core are "held" in place. When you energize the coil at this moment in time the coil will act like an air cored coil, that is permeability = 1. This low permeability will cause the current to have a very fast and high rise time if not limited by resistance. Now as the magnets move away the dipoles are no longer held by the magnets so they relax but only to find themselves in yet again another magnetic field (of the coil). When the magnet is fully away the coil will have a certain current and inductance, this equates to a certain amount of energy given by Energy=0.5*Current^2*Inductance.

Steorn claims ,and I can agree with it, that that inductive energy is much high than the one you gave to the coil when it had low inductance. Here's a technical example:

Imagine when the magnet is close by the coil acts like it has 1H of inductance. And assume that we let the current rise to 10 A. This will give us a total Energy input of 50 Joules.  Now when the maget has moved away the inductance has increase but the current remained the same. Let's say the inductance increased a 100 fold which is moderate, this now gives you a total inductive energy of 500 Joules. This is an increase of 100x to the inputted energy.

Now this is the theory. Jnaudin showed an intresting experiment concering inductance and distance from magnet which seems to be counter intuitive:

You see as the magnet comes closer the rise time stretches out which would indicate an increase in inductance and as the magnet moves away the rise time becomes much shorted which indicates a decrease in inductance, this is opposite to what I said above. This may be attributed to magnetic viscosity if jnaudin can show the results at different frequencies. I would think at lower frequencies it would behave as speculated above.

In the orbo the only energy you will lose for good is the ohmic energy.

I think you're right on the money my friend.

Now, how can we create a testable test to explore that effect?

Fausto.

  Stephan has always let the dissection go on and on, I think he is more than fair. M/H repeated his anti OU anthem over and over endlessly. There was no dissection just the same nothing to see here attitude ad nausium.
   No Great loss there as I'm sure there would be no great loss if it were me but hey I like it here so I'll keep it humble.

    I'm afraid I'll be showing my lack off electronics understanding by asking questions but I really want to understand so be kind please.

    Am I correct that a toroidal coil with the proper windings and current run Thru it effectively cancel a magnetic field allowing magnetic coil to get past the sticking point and proceed to the next movement point? Kind of like the ever elusive 1 way magnetic shielding?
   I know its much more complex than this but as I said I am 1 notch below novice and if I'm missing the point could you help me out.
    thanks Pete

Yes it could and that opens another door!!!!!

Is there anyone out there that can verify the lowering of inductance as the magnet passes by? Although this is very interesting, I'm still trying to wrap my head around it. Any thoughts from anyone how to improve upon what was stated?

It's the *effective* permeability that changes. That's well known about.

Again, since the beginning Sean @ Steorn has said the key is magnetic viscosity.

Took one of my fans apart (from a failed bedini exp) and noticed the holes in the fan are premarked! I was thinking it was going to be tedious marking out 8 holes in such a small area.

Hi Jimboot!

Yes my fan rotor had eight holes premarked inside as well! I don't know if they were perfect but my bolts didn't come out too well in terms of alignment so it may have been my drilling. But I got around all that as previously described and alignment is great now!
