Splitting the electron stream

  I'm neutral on this one, but that was an impressive reply GB, thanks for staying out of the mud.

That's why I said to disconnect one of the coils shortly after the beginning of the pulse, you dumb ass.  After you disconnect one of the coils, then it's no longer acting as a bifilar coil and is no longer self cancelling, you dumb ass.  The current is flowing in opposite directions in both coils at it's maximum value allowed by the resistance almost instantaneously because there is no net inductance, you dumb ass.  After you disconnect one of the coils, then you'll have a net magnetic field and a net inductance, but the current is already at it's maximum value, you dumb ass.  The end result is charging the coil with 0 inductance which allows the current to reach it's maximum value almost instantaneously with a net magnetic field after one of the coils is disconnected, dumb ass.

Apparently you do not know what a bifilar coil is dumb ass.

Take a piece of wire, fold it in half and start winding at the fold. That is a bifilar coil and they are typically used to induct electrons off a resonant coil below them dumb ass.

A volume of your BS exposed and that was all you had?

I noticed you forgot to mention anything about that old amp meter blowing your magical thinking out of the water. How about those clearly visible extra coils embedded in the plastic of the Steorn you can't seem to address? Oh... Dumb ass.

I coughed up part of a lung laughing about that one. I love sarcasm.

Where is the Slorbo replication? Dumbasses

There are different types of bifilar coils, http://en.wikipedia.org/wiki/Bifilar_coil

Some bifilars have adjacent coils in which the convolutions are arranged so that the potential difference is magnified (i.e., the current flows in same parallel direction). Others are wound so that the current flows in opposite directions. The magnetic field created by one winding is therefore equal and opposite to that created by the other, resulting in a net magnetic field of zero (i.e., neutralizing any negative effects in the coil). In electrical terms, this means that the self-inductance of the coil is zero.

It doesn't matter how the coils are wound, as long as there is 0 inductance at the beginning of the pulse, and a net magnetic field and a net inductance after one of the windings is disconnected.  Cut the wire at the fold, now you have two wires and 4 ends.  It doesn't change anything.

As far as the amp meter showing current flow isn't all that unusual in a PMH, because some materials will slowly lose their magnetization over time, especially if there are tiny gaps between the keeper and the "U" legs on a PMH.  If there's a small amount of current flow, then it's dissipating energy and losing its magnetization over time.  Disconnect the keeper, then most of the energy will be dissipated at once and the PMH will be at H_c.  That's why a LED will light when the keeper is pulled off the PMH, because it's dissippating most of it's energy at one time.  The best PMH is one that has no current flow, thus it will hold its charge for a long time.
