[@leibel1498]

@@TechIngredients Thank you for your very educational and interesting videos I really appreciate it, but shouldn’t the effects of two magnets simply be the effects of the first and second magnet added together, I’m assuming that the charges/poles in a permanent magnet are fixed and don’t move in response to the field of another magnet, so shouldn’t it simply be a matter of adding up the force vectors (e.g. if two forces are equal but at right angles to each other then the final force should be 1.414 times as strong)

Is there a maximum theoretical efficiency to these types of generators or is it only limited by the magnetic field strength?

[@TechIngredients]

I'm sure there is, but the big hump that must first be crossed is the avoidance of electrolysis. It takes a lot of energy to tear apart the oxygen and hydrogen in a water molecule. Expelling this gas out of the generator unused, is costly. The trick is keeping an individual MHD cell at or below 1.2V of potential. Controlling the field, the velocity and possibly resorting to parallel cells operating in series are potential solutions.

[@avael2451]

@@TechIngredients I've noticed there's a lack of information on it outside of acadamic resources, and much of that is based on more advanced magnetic resonance techniques than just aquiring CW signal, free induction decay, or a chemical shift specturm. There's a large number of papers and books published in the 70s and 80s particularly by organic chemists who due to financial constraints at the time built their own fourier transformer NMR spectrometers using quadrature detection and other techniques common to amateur radio yet not so much in the modern engineering world. I don't have a signal generator or spectrum analyzer so I can't conduct any magnetic resonance experiments until I either build or buy those peices of equipment. It seems pretty straightforward to do a demonstration of it and the existing resources, especially on youtube, either involve superconducting magnets used in organic chemistry research or are of poor quality.

since we are talking magnets i got an idea for you, a Linear Permeant Magnet Mass Driver, the magnets are arranged such that they retract or brake away from the barrel as the projectile reaches set points along the acceleration path, so that the magnets do not hinder the forward velocity of the projectile. The magnets will operate on a trigger mechanism that are spring loaded such that they spring away very fast thus removing their influence on the projectile as it pass the magnet.

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 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).

[@TechIngredients]

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.

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.

I'm pretty sure this channel doesn't attract many Juggalos lol.

5:56 "...constructing a little magnetic yoke." No, thanks. I don't want all my eggs pointing north! [groans]

"Those are forces!"

[@ThomSteff1]

Thanks for your great work. What is that water tank in the box?

[@MrRolnicek]

Speaking of powerful magnetic fields, I don't suppose you can get your hands on some Rebco superconductors, can you?

[@williamkaukler9202]

This is 2 years old...where is the next part of the build? Would like to see liquid metal moving. I recently have a project working with such pulse currents, z-pinch, high speed switches etc. and found you were looking at liquid metal unlike others.

End of the tip where the balls are. Hehe.

[@SixTough]

Nice

[@Nevir202]

Wait, after all this, did he never do anything with it? It’s been almost a year.

[@TechIngredients]

I'm very busy, but slowly the projects involving that magnet are moving forward.

[@MrAlbinopapa]

Was wondering the same, glad to see a quick response. Very interesting videos, I especially liked the speakers made from "trash" concept, might actually have to try it myself.

[@MindKontrolleProject]

Cool... what would you estimate the speed (if measured) of the magnetic attraction you had during the insertion of the magnets into the yoke?

God I am just DELIGHTED that this level of content is still available out here.

Camera work is nauseating.

[@tonyhallen1062]

is the magnetic field of a magnet made up of discreet entities referred to as lines, or do lines represent an average stregth of a homogeneous magnetic field at an arbitrary point?

[@TechIngredients]

They are imaginary constructs that help us visualize the field interaction and its strength.

[@brentcairns3900]

How the yoke design translate into a disk configuration? I am trying to maximised the magnetic pull of an Axial flux permanent magnet generator, for a wind turbine. Using a 40x20x10 N52 magnets, I assume the disk where the magnets are fixed, needs to match the thickness of the magnet, namely 10mm. The perimeter of the yoke to be the same, at 10mm & the gap between around the same?

[@TechIngredients]

I can't address the gaps in your design, but the thickness of the steel should be at least equal to the thickness of those magnets.

[@victoryfirst2878]

I am just amazed at the strength of the magnetic box you made Tech Ingredients. Look forward to see more great things from you soon !!!!!!!!

[@WildRapier]

I've worked with those magnets during a pilot program at a wastewater plant for magnetite ballast recovery. They are finger smashers. I'm surprised you were able to get them together without annihilating each other. I saw the remnants of 2 that someone got a little too curious with. Watch your fingers, phones, computers, TV screens..........oh and any credit/debit card. Not sure if they can wipe a chipped card. It was a few years before chipped cards.

People can be severely injured by these magnets
