Hey everyone, pay attention. This is a world premiere. I'm proud to present the true 3D magnetic field of a Halbach array. It looks like a magnetic monster, doesn't it?
If you want to fully understand what's going on, I strongly recommend watching this video where the discovery by Marcio Silconi and his work on magnetic orbitals is explained in detail. Using his innovative method, he managed for the first time to reconstruct the true magnetic field in all three dimensions of the most famous magnetic sequence in the world, the Halbach array.
This sequence has an almost magical property. It amplifies the magnetic field on one side while reducing it on the other. If you search online for representations of this field, you'll usually find this image from Wikipedia. The problem is that image doesn't tell the whole story. It's essentially the same situation we discussed for a single magnet. Field lines going from north to south and textbooks always stop there. But with this discovery, we now know there's much more beneath the surface.
The magnetic field can be unpacked based on the measurement angle, and this gives us the ability to understand and even predict all possible interactions between magnets following the geometries that naturally emerge. At this point, Marcio asked a very simple question about the Halbach array. How is this magical field enhancement usually exploited? And of course, the answer is in this direction. So, he applied his fixed angle method exactly along that direction. And what happened next is something you need to look at very carefully because the live measurements are genuinely shocking.
Guys, before we dive into the analysis, just a quick reminder. The discovery of the true magnetic field, book available on Amazon. This research was not funded by any university, institution, or organization. Three years of work, experiments, failures, long nights, prototypes, measurements repeated countless times. Everything carried out independently. And despite that, the full work was published open access so that anyone can download it, study it, and verify it freely.
At this moment, the most direct way to take part in supporting this extensive effort is through the printed edition of the research. A carefully crafted volume with all magnetic field images presented in high quality, immediately accessible, meant to be browsed the way one handles significant scientific works. And not to mention the cover. Take a look. Minimal, subtle, sci-fi aesthetics, a luminous logo emerging from a black background designed to stand out on any bookshelf. This is not a book you read once and forget. It is a book you keep, one that stays. Consider it. The link is in the description. And thank you for your support.
By now, you already know the method, so let's speed things up a bit. >> [music] [music] [music] [music] [music] [music] [music] [music] [music] [music] >> All right, this is seriously strange. This was one of the most difficult measurements Marcio has ever performed. But now, we can understand much more. For example, take a look at the number of polarities on each side. Here's what happens. Finally, something important starts to reveal itself.
On the side where the field expands, the polarities seem to coexist naturally. Look closely. There are three norths and two souths, and that's exactly what we observe [music] through the magnetic field itself. We can also see that the polarities begin precisely at the midpoint of the magnets aligned along the horizontal axis, and even though their orientations differ, polarities with the same sign merge with their neighbors, reinforcing each other.
On the opposite side, however, something very different happens. A kind of interference emerges between the polarities, leading to a reduction in field intensity. In fact, this representation of the field becomes highly irregular compared to the magnets generating it. Look at this, [music] right here. There's even a small south polarity bubble trapped inside a north polarity region.
After that, Marcio continued by measuring the field at different distances using his magnetic CT scan. >> [music] [music] [music] [music] [music] >> And [music] now, take a look at this. This is the second map. What? I mean, what? This is what happens to the magnetic field of a Halbach array when you start moving laterally away from the source. Compare the two maps side by side, they look like they belong to completely different realities.
See how these four south polarities merge here, becoming two with a very unusual shape. And then, even more surprising, all the lower bubbles merge and turn into this, something that looks like a pair of beans with a central polarity flipped in between. And all of this happens over a distance of just a couple of millimeters between the two measurements. The first one, as you saw, was taken with the magnets on the upper plane. The second one with the magnets on the lower plane, practically touching the upper one. The distance between them was just the thickness of the plane itself. And yet, all of this happened.
Now, let's move on to the next maps. This is the third one. >> [music] [music] [music] [music] [music] [music] >> And here again, we can observe a significant change. The merging of the red interactions, which as you can see is not just theory, it's physically real. By increasing the distance further, Marcio completed the full magnetic CT scan. >> [music] [music] >> Here it is, shown in sequence. You know what it looks like? Something almost molecular in behavior, don't you think? Or maybe even closer to a fluid than to a magnetic field. It's beautiful. There's a kind of hidden choreography in there. Like the field is negotiating with itself.
And now, we can finally compare this with the image typically shown on Wikipedia. Do you see how much more informative and revealing Marcio Halac's representations are? With this approach, we can precisely identify every interaction point the field will generate when used in real applications. And that means one thing. We can exploit its full potential with far greater [music] control and understanding.
As we've seen, here is the 3D reconstruction. And we'd like to dedicate these reconstructions to Dr. Halbach as a way of honoring his work. But wait. In this reconstruction, the layers have been slightly spaced apart to make them easier to study. When we look at the measurement with the real distances between the layers, it appears like this. Everything becomes more compact, more condensed, like the field is holding its breath.
And of course, we couldn't skip the manual construction of the Halbach array. This time, Marcio went for an accordion-style design. Pretty cool, right? And if you think we're done showing you astonishing things, you're completely off track. If you want to be among the first in the world to see what comes next, like the video, share it, subscribe, and turn on notifications. That way, we'll become a magnetic family teleporting straight into the future. Greetings to everyone from X, your favorite scientific alien.
