More on Magnetic Fields
(8) CommentsMore detail from LPP’s March 31 report:
In our continuing tests of the influence of small axial (vertical) magnetic fields on the DPF and the angular momentum of the plasmoids, we noticed that the influence of the axial field coil (AFC) seemed to be shifting with time, and the control shots (with the coil turned off) kept getting better and better, as if FF-1 was remembering the effect of the magnetic field. Indeed, that turned out to be the case. The steel flanges that attach the vacuum chamber to the inner lower bus plate which supports it, and the plate itself, were both becoming magnetized by the field produced by the AFC, producing a magnetic memory. These fields, now produced by a permanent magnet, were considerably greater than the field we started with, created by the earth’s field. We measured these fields and found that they are nearly triple the 0.17 gauss we first measured between the electrodes of the DPF.
We now find that the control shots (which are no longer controls because of the permanent magnetic field) are producing about 10 times as many neutrons as the control shots generated before we magnetized the flanges. This is additional evidence that the predicted angular momentum effect, in which the small fields add the spin needed to make a large plasmoid, is working. However, more tests will be needed to confirm these hypotheses, and we will have to carefully take into account the permanent magnetization we are creating. In the future, we may find it desirable to replace the flanges with those made from non-magnetic alloys of steel, but that will not be done in the near term.

For a more in depth discussion, start a thread in the forums.You can also use the same coils to demagnetize your experiment before firing control shots. Use the same kind of demagnetizing circuitry as being used in old-fashioned color TV’s. In essence a diminishing AC current.
google for “degaussing” or “demagnetizing” to find answers.
What an interesting outcome. I wonder how much of this was anticipated in the original design of the tool. I’m referring to the coil ultimately magnetizing the flanges. Was it a simple oversight/under estimation, since most if not all previous DPF experiments have not included an AFC component? If it was, its a very fascinating discovery event.
Hey belbear, it beginning to sound like you need to work for the team. You have my vote.
Glen! Where are you? Have you gotten any of those messages? We need the T-shirt art.
I’d love to, but unfortunately I’m living at the wrong side of the Atlantic to take this on as a weekend job…
What messages?
I sent a few to your email, your private messages via clicking on the link of your name. Posted to the T-shirt thread, and finally, posted this thread: http://focusfusion.org/index.php/forums/viewthread/496/
The message is that I don’t have final, print quality artwork you made for the T-shirts. Cafepress has them, but won’t give them to me (“we’re not a data storage and retrieval company,” they said). I’m hoping you still have the original artwork. Say you do! And send it over. We’ve got bandwidth now.
Hello? Hello? Glenn?
