Fun with magnets; was RE: [Vo]:Magnetic viscosity question: generating a harmonic frequency
I have been doing many experiments with magnets recently, and have hundreds of the most powerful magnets available from e.g. http://www.forcefieldmagnets.com/catalog/index.php http://www.supermagnetman.net/ http://en.wikipedia.org/wiki/NdFeB#Other_dangers http://www.kjmagnetics.com/proddetail.asp?prod=BX0X0X0 http://www.magnet4sale.com/home.php http://www.unitednuclear.com/magnets.htm If you haven't experienced these rare earth magnets, I think you'll be in for some surprises! Be very careful with these. Ideally you'll need a special workshop with only non-magnetic materials around, such as titanium tools, and wooden workbenches, no computers, disk drives, credit cards, etc. nearby, and practice being aware of what you're doing. You must constantly think about what you're doing, as if you're carrying around U235 or nitroglycerine ( I know, I've had numerous close calls, pinched fingers, and shattered magnets, sucking up tools from a foot away, getting stuck to a vise, etc. ). The forces can be in tons for two magnets with 1.2 Tesla flux densities (12000 Gauss) at their surfaces. I've had to build a special tool to separate two magnets that got accidentally got stuck together: http://www.kjmagnetics.com/buildamagnetseparator.asp Hoyt Stearns Scottsdale, Arizona US http://HoytStearns.com
Re: [Vo]:Magnetic viscosity question: generating a harmonic frequency
From Hoyt: Very interesting speculation. Thanks. From tests I have done, Sv can be from microseconds to seconds depending on the material. It's on the order of a millisecond for Nd2Fe14B. Hoyt Stearns Thanks, Hoyt, From microseconds to seconds. Wow! That's a huge range! I would seem logical to assume that the majority of the Neodymium family of PMs would share, roughly speaking, the same viscotic characteristics - on the order of a millisecond or so. This is just a guess on my part, but I would speculate that ferric and ceramic PMs are likely to cycle much more slowly than Neodymium PMs - on the order approaching a second. I wonder if the size of the PM can make a difference as well. Would you agree, or not. Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks

I think this issue was addressed by an experiment in fizzx.com, a spin-off of the Steorn forum. It would have been in one of the Whipmag threads. If I have time today, I'll see if I can find it.

From what I can tell, visually speaking, I don't think the sudden rotational increase is due to an unconscious manual pumping of the PMs introduced (unintentionally) into the configuration by the user. The spinning I've seen occurs where the user is no longer manually influencing the configuration. The contraption is spinning freely on its own for a few brief seconds.

Re: [Vo]:Magnetic Viscosity
They *must* use resonance in a solid state version. This is what had kept bothering me was the subtle hints of a solid state ORBO (realORBOllocks). I believe that using a cross-field interference alignment they can maximize the domain flip efficiency. H. There should be an optimum frequency for spinon depletion that could be determined. Or maybe that is not domain-related. You know that Sean denied Barkhausen effect played any part in his technology. However, Barkhausen domain flipping and renormalization is the calculus of magnetic viscosity. Regarding the Chladni Plate, here's a HUGE coincidence. My other hobby involves the Knights Templer (long before the DaVinci Code, BTW) and you can see how the mystery musical codes of Rosslyn Chapel are explained on the video on this site: http://www.tjmitchell.com/stuart/rosslyn.html (scroll down). The images are just those resonant images you referenced!!!

The electron spins in the material don't change instantly when the applied field changes. Example, say an applied field is saturating the core to 99.9%. Then within 1 ns the applied field is completely removed. Most magnetic cores cannot react that fast. So it might take 100 ns for the core to change from %99.9 saturation to 10% saturation.

Okay, for a fixed field strength, it takes time for the field density to catch up, so to speak; hence, viscosity. Whereas, hysteresis relates to varying applied field strength. So, Steorn claims that their technology takes advantage of magnetic domain alignment time lag. Terry

Regards, Paul Lowrance but that's the mechanism of magnetic refigeration. If it's that simple the people doing magnetic refrigeration will have a fit.

[Vo]: Magnetic viscosity questions
I first heard about magnetic viscosity (V[s])a few weeks ago. As I understand it, there's a time delay in ferromagnetic materials between an applied H field and the corresponding B field (and in reverse also -- removing the H field). If I spin a magnet over a ferromagnetic disc (assume non-conductive), I would think that without magnetic viscosity, it would just be attracted to the magnet as if it weren't spinning. With viscosity, I'd expect an angular difference between the magnet's flux lines and the induced flux in the disc. As the speed increases, it seems the phase angle would exceed 90 degrees and the disc would be repelled. Has that been observed? What materials have the highest V[s]?
