[@quantumrandomness5114]

whenever i saw the refrigerator magnet part i instantly decided to see the effect for myself. i found that not only do the magnets allow for only movement in increments but it the magnets also weaken if the fields are at a 90-degree angle to each other kind of like when you rotate a polarized lens 90 degrees to another polarized lens, and it blocks the light from passing. but in this case the magnetic field getting weakened is like the like getting blocked

They're called correlated magnets. My late friend Larry Fullerton invented this technology. Glad to see it trickling out to the masses.

[@nesdi6653]

That's wild that it took us this long to figure this out. Like simple magnets! This isn't like the hadron collider nuclear molicules thing theyre just magnets.

[@hikingpete]

I'm not sure about Larry's contributions, but the Halbach array that makes up fridge magnets has been around since the seventies.

[@bkucenski]

Fullerton invented the programmable magnet in 2008. Halbach arrays are individual permanent magnets arranged like he showed in the video. Being able to program a single magnet with complex patterns of polarity is what Fullerton figured out. Fridge magnets are polarized by being passed over a halbach array to imprint the pattern. So there is a significant difference. Halbach arrays are permanent magnets. Correlated Magnets are programmed with electromagnets at a much finer and arbitrary detail.

[@EnZodiac]

So they're basically magnets within magnets

[@bradleypmayo]

@@nesdi6653 the humans on earth now recently figured it out. More and more ancient stones that have correlated magnetic fields are turning up all over the world. The problem being, most archeologists don't know anything about magnets!

[@BariumCobaltNitrog3n]

I have some of these magnets. The magnets that repel when you twist them is a cabinet door latch and the smart one with the tiny field lines is to hold a cell phone on the dashboard, where you place the metal plate inside the back (or attach to the outside) of your cell phone's case. The magnetic field doesn't go through the plate into the cell phone. The magnets that click and hold only in certain spots are for drawers on boats so they hold in almost any position, and the magnets are bars instead of circles, so when you open it, it will stay in place while you look into the drawer, then almost closed, then closed. The ones that repel until you push them together will keep a window open just a little bit, but latch it closed when you push the window down with no mechanical parts. These magnets are pretty cheap too, only a few dollars each.

[@nicholasweiss4662]

Thats interesting. You actually explain one thing I felt was missing in the video: What real world applications these have. For some, like the ones that release when twisted were obvius to me, but i did not figure out what those that repel unless forced together could be used for.

Nobody can even fully comprehend how this guy without knowing it , is making the human mind evolve at a global scale . And he do that very quickly and consistently . it's amazing . hundreds year from now . the first basic idea of thing used in those years could come from one of his video . a six grader could see this and say to himself , wow i wanna know more about magnet . and 60 years from now he may discover something that would be used 40 years later to create ground breaking technology . We somehow think we know everything there is to know , but we really don't , we don't know more, then we know , every answer give multiple new question . The more we know , the more we realize that we know even less . So it's perfectly conceivable that my story could happen , that video gave me more question than answer , and maybe those question won't be answered in my lifetime . Instead of producing highly developed and educated people ,school still create low wage worker , and radical people , politic and "sex" is becoming the subject of choice . when we should be teaching all the new generation , way more stuff , at least they have internet so they could seek it easily , but still we have to teach them quickly how to look for the information they are looking for , or the information that can enlighten them . Make them think , and give them a good base on LOGIC , and fallacy . Anyways weeds is doing its effect , i'm writing a book again ... have a nice day .

I remember seeing a video from a company that was printing magnetic patterns. I’ve thought about it often since and have always thought that it was probably one of the bigger breakthroughs in recent history. I feel like control and manipulation of magnetic fields is going to be critical in our species pushing through the next barrier in our technologies. I find it so exciting watching these and thinking, there’s a child somewhere watching this video, who in the future is going to be stuck trying to push the limits of science and will remember this video as a solution to a problem we currently can not comprehend as we’re just not there yet. Love the videos, you’re such a positive force in this space!

Its of course nothing surprising or special or anything, a million people probably discovered this can be done or maybe it wasn't anything that was hidden from the start ( and I had just never seen one before, realistically I didn't even know fridge magnets worked like that tbh) but the fact that they work this way, Idk my face is smiling I'm a little kid inside, perhaps I've always have been, I love stuff like this, I always have.

This is super cool! Now I’m wondering if you could make frictionless gears and joints with this. Or maybe you could apply the smart magnet ability to super magnets and figure out an arrangement to make the best and smoothest shock absorbers ever. I'm picturing a motorcycle with the body and wheels being completely detached and the body just hovering over the wheels. Or like one of those sci fi robots with the floating limbs and split torso. Super Smart Electromagnets would pretty much let you suspend anything from anything else if you could make it efficient enough. That would be sweeeeeetttt!!!!

[@darksunrise957]

Huh, you just made me realize how much this could revolutionize the magnetic gear industry. They have a variety of uses, but are currently VERY expensive, considering they're made from hundreds of small parts and magnets adhered together.

That smart magnet with the 'ridges'... Because of the alternating N/S, the magnetic field only pokes out a little bit. But what happens to the edges? Won't the magnetic field just loop around and into the other side of the magenet? Why doesn't it show on that magnetic viewing paper?

[@talbrightmoon2625]

I'm wondering if the side/length of the polarized areas are controlling this. Like with the ones that repel at a distance, one pole was larger and encompassed the inner pole. With the alternating pattern, does the length of the pole need to be relative to the one beside it? (See the pattern during the shielded segment).

[@Macialao]

Is it due to Pauli exclusion principle? There are always free orbitals (free pairs, or antibonding orbitals) that can be filled, i don't see any spin related. But, coulombic interaction between nuclei are the ones that are repulsive, or rather have tremendous activation energy to form nucleonic orbitals (basically nuclear fusion).
