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
Re: [Vo]:Magnetic viscosity question: generating a harmonic frequency
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.

My apologies up front if not. The following two questions are related to each other: (1) Does anyone know how fast magnetic viscosity on average tends to propagate (or cycle) through various kinds of permanent magnetic material? Hundredths of a second? Milliseconds? Microseconds? Faster or slower??? (2) Is it theoretically possible to generate a viscosity induced HARMONIC frequency in a permanent magnet. I'm speculating on whether an amplified harmonic effect could be generated by a carefully applied external frequency, such as an external EM field set to a specific frequency, or perhaps through an assembly of rapidly spinning permanent magnets such as one finds in a spinning wheel. I'm speculating on whether it's possible if certain externally induced EM frequencies might enhance the viscotic migratory effect within certain permanent magnet materials. It's analogous to how lasers produce light through a buildup of specific EM harmonic frequencies within the crystal that ultimately produces a strong coherent beam of light. PERSONAL THOUGHTS: If specific harmonic magnetic viscosity fields can be enhanced or possibly amplified within certain PM materials the implications could be interesting. One of the reason's I'm posing this question in Vortex is that there are various You-tube videos I've seen out in the public domain that hint (at least to me) of the possibility that the user may have accidentally stumbled across for a brief period of time just the right magnetic viscosity induced frequency that caused their magnetic assembly/contraption to spin up for a few brief dramatic seconds. However, because they really don't know what they are doing it's all very unstable and soon the assembly eventually gets out-of-phase, harmonically speaking, causing the assembly to grind to a halt. 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. Of course, this is all just conjecture on my part. Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
