I know this is way off topic, but would it be possible to use neodymium magnets in dentures to keep them forced apart - pressed against the gums? I'm very curious to see if it would work, but only if the repulsive force would even theoretically be enough. I haven't been able to locate neodymium bar magnets that weren't magnetized along the short axis in order to test the push effect with any incidence of attraction getting in the mix (as teeth also move side to side when grinding).

+Tech Ingredients Plastic spoons only (you could always do that "spoon on cheek trick HAHA) . Yeah, I'd thought of the geometrically increasing repulsion and don't really know how much of a problem that would be. They'd probably need to be well engineered for each person's circumstances. For me perhaps a short upper plate magnet and a long lower plate magnet would travel more in parallel to the force lines to provide a more uniform push against the opposing plates. On the other note, I'd expect that being embedded in the acrylic it would not be subject corrosion. Thoughts? BTW, thank you for replying. Your videos are awesome!
Tech Ingredients

Yep, that's a little outside the usual envlope, but that is where just about every innovation originates. There are too challenges as I see it. The least is the susceptibility of neodymium to corrosion, the magnetswould have to be well protected. More problematic is the geometricly increasing repulsion. With your jaws far apart, the retaining force will be at it's lowest level, but you might find it difficult to approximate your teeth in order to chew. Also, strong magnets in your mouth would be a hazard if any feromagnetic objects got to close to your head.

The highest magnetic field that can be created using Neodymium magnets is a 3.2 Tesla magnetic field. That is if the circuimstances are perfect. And the configuration is right.
Tech Ingredients

You are correct, if you not only use a yoke, but also use pole pieces with a high saturation limit to concentrate the field beyond the field present at the surface of the magnet itself.

Take a look at that exact point in the video again and watch for 22 seconds. What I said is true when THE MAGNET is the same distance from the steel balls. The bar acts as a transmission line for the field. Sorry you found it too slow, but you might want to at least recheck the part you mentioned because the principle is important.

The utility of the electromagnet in full view. You could place all the electromagnets with power off. Much less dangerous. . . .
Tech Ingredients
Tech Ingredients 19 дней назад
The field strength levels you are aiming for are very high. Permanent, non super conducting magnets are a non starter. Steady state electromagnets will also not be able to reach anywhere near that level. Pulsed electromagnets will get closer, but still be unlikely to achieve those levels. My advice would be to establish the minimum field that will allow your project to proceed and then attempt to construct a small test magnet and see if you can at least generate that minimum field.

+Tech Ingredients I'm building a home-made NMR device (nuclear magnetic resonance) to test figure 7, page 5 of the patent below. I'd love to use a permanent magnet because I'll otherwise need LN2 or liquid helium for an electromagnet. Although you can use extreme focusing tricks with pyramid shaped permanent magnets and get a high static field, the effective volume is too small due to all the focusing. So I'm searching for ways to produce a static (DC-based) magnetic field without cryogenics but also without burning up the electromagnet. It's too bad you cannot create 5 Tesla, 10 Tesla, 20 Tesla permanent magnets of a workable size. No cryo would be needed. This patent uses NMR to polarize/align the magnetic moments of 1/2 spin atoms (bismuth in the patent's case) then oscillate them. Figure 7 on page 5 is a cutout of a spherical bismuth crew compartment. patentimages.storage.googleapis.com/3a/e1/0a/cdda5bf4825fb1/US3626605.pdf I won't know how high a (DC) static field I'll need until my homebuilt NMR is finished, but I want to have the freedom to crank it up to 20 Tesla. Having an electromagnet for such high fields is safer anyway, it can be shut off easily. . . .

There is that, but everything is a trade off. The permanent magnetic assembly has a more stable field and consumes no electrical energy. If this magnet is being used for an MHD pump or generator, an electromagnet could be a deal breaker.

Would the maximum efficiency of a space be found in a construction with poles facing inward in the shape as close to a sphere as possible? So two magnets face each other = increase. What about 3? What about 4? What about infinitely many oriented with their opposite poles facing each other (as nearly as possible)? Or cylindrical?

That design is probably OK, but with rapidly diminishing returns. The magnets will begin crowding each other out and the increased number of magnets will be balanced by the ever increasing distance of the magnets from the center of the assembly. A gap with a heavy yoke with two conical steel pole pieces within the gap to further concentrate the field is probably the best realistic solution. You might want to try playing with this tool: www.kjmagnetics.com/gap.calculator.asp

Everything at quantum level is a magnetic domain, as you call them. Toroidal structures acting as little pumps within and upon an ocean of potential. Think fluid dynamics and remember all the magnetic funny actions. No need for such notions as quantum weirdness. No need for notions of a need for a unification theory. The universe is much simpler than most can fathom. Simple is more stable and likely, is it not?

+Tech Ingredients In open air the magnetic field around the point of a tapered parallelogram often hits 7T. I would presume more. for a yoke by more than double. Sadly somewhere about 12T to 14T you get failure of magnet structure. You might do better focusing using Mu Metal it is spectacular. Let me make it clear 1.2 T is not that high. I get nearly 2.4 T inside a motor I have built. Using Mu Metal I could easily get 5T. That 2.4 T is using standard M15 steel. N-50 magnets in the tapered structures get easil 5T or 6T and sometimes 8T. Maybe I didn't make myself clear on this but 1.4T is trivial in magnetic fields. Cryogenic stuff really goes up there. The problem is about 12T the crystal structure of the magnets pulls apart or crushes. I would suggest that if you approach above 6T you look into concentration using 49% Cobalt 49% Iron and 2% Vanadium Alloy or the Mu-Metal.. It is the best for concentration. If you are only getting 1.2T then all you are getting is direct magnet to magnet N-50 N-52 magnets. There are magnets up to N-75 and N78. (Very expensive) . Do understand that N-52 is not 52/50 ratio to N-50. it is nearly 4 times. These really get amazing. The biggest problem is to install these magnets in the structure without damage. No you can get a lot more out of a N-50 magnet than the 0.65 T that is does on a flat surface if you shape it. You can get using an area reduction from 4 square inches on one face to 1 on the other face a flux density gain of nearly 4:1. That would be in your pole to pole functions approximately 4x 0.65T x 2 or 5.2T. If you jam it in taper up you can get it upwards of 7T.
Tech Ingredients

We are currently achieving 12,000 Gauss or 1.2 T in the yoke we demonstrated. Neodymium magnets cannot exceed 1.4 T without high saturation, steel pole pieces between the magnets, within the gap and this is over a very small region in the center of the gap.
Paul Noel

Could you explain the convention of magnetic field 'lines'? I was taught (admittedly, several years ago), when pursuing a degree in electronic engineering, that magnetic field lines did not exist. But was rather a man-made convention, (largely inferred from early experiments) of the manner of which iron fillings appear to align themselves via magnetic induced polarities, along a gradient path... In effect, a field is a smooth magnitude gradient with no inherent lines.
Tech Ingredients
Tech Ingredients 3 месяца назад
Personally, I believe the best way to clarify this is to ignore the iron filings. I'm not being factitious. The material interaction between the individual iron particles includes friction and the unsymmetrical shape of the particles. When a particular series of these needle-like particles achieves a closed loop from the N to S pole, the field will be guided or concentrated within this pathway, just like in our yoke and the field strength on either side will be lower thus discouraging the development of another series adjacent to this loop. The field is smooth and continuous unless there are objects in the surrounding environment that disturb it. The filings modify the magnetic field distribution and then go on to show the effect of this modification. This is like the man convicted of killing his parents and begging the judge for mercy because he is an orphan.

James Tuller

again, a magnet moving near a conductor (electrical ) or a conductor moving by a magnet, induces an electrical current in the conductor, even your steel box or tube is a conductor. You are inducing opposing forces, reducing efficiency
Tech Ingredients

You are correct, but what matters is...is it significant? Please provide some equations that allow us to quantify or even estimate the magnitude of loss.
James Tuller
James Tuller 3 месяца назад
Again don't use conductive (electrically). Magnets moving near a conductor even non magnetic material build up a current which sets up a magnetic field opposite to the magnet even though the conductor is non magnetic.
James Tuller
James Tuller 3 месяца назад
Of course if there is any movement of magnets the current induced in the electric conductive material of aluminum will set up an opposing magnetic forces. Perhaps some strong plastic would be a better choice as neither magnetic or electromagnetic or electrically conductive which may be hinderance.
