So Iāve now ordered some more practical 3mm cubes. So ill up the size to 3 x 15mm Iāve also ran some some simulations to see the field. ( overcomplicated bs. Just give me shapes and some wiggly lines ffsā¦ )
Iāve also cadded a case to assist with sticking them togeather for gluing. And Iāve also designed an semi open capsule . No glue required. Iāll be able to test a diametric. Axial and hallbach array side by side to see if thereās any real world potential to dangerous and precautiously sticking aposing magnets togeather.

Letās talk science. This guy measured some arrays. Standard. Hallbach. And hallbach iron backed. I was considering a back iron. To assist with fixing and inproved preformance. But its shinanigins is only improved slightly.
If you have any sugestions to try during the experiments let me know. Iām about to jump down a pyramid magnet rabbit holeā¦

So overall it looks like you can get significantly stronger fields at very close proximity to the magnetic surface using a Hallbach array, however the field strength falls dramatically with distance (as expected) until your gains are likely not worth the physical volume required by the array itself. In short, this means lifting power is enhanced considerably but field āreachā (distance) which might be useful for sensing applications will likely be offset by the considerable brick of magnets you have to use to achieve this.
Or you could just get an m1448a

Valid. when lifting . arenāt you capitalising on close proximity? So from a purely lifting standpoint a hallbach may be advantageous. But how much more advantageousnessā¦ this i hope to measure. Using 5 cube magnets in each array in hope to measure or quantify the difference between the arrays. Using the cubes as a control of sorts..

I do think with your specific constraints a Halbach array of cubes vs a straight bar magnet of the same length and width dimensions would be advantageous and not take up any more physical volume.
Also, if you want to get an idea of how the magnets might work when under the skin, I would play it safe and use three bandages / plasters stacked overtop each other to add just that little bit of extra distance. That should give you a more conservative approximation of subdermal performance of a resin encapsulated magnet array.

Awsome. Iāll keep yall posted and ill try make a snazzy video of the experiment. For shits and giggles. Place your bets nowā¦

But how much more adventageousnessness?

Check the graph in that guyās video.. with 1mm I think it was a 93% improvement. Skin is 2mm typically so probably around 75% adventageousnessness.. roughly guessing
