This is the axial… ive printed new cassetseach array fits in a bit of wire shrink wrap nicely. I’ll knock togeather the other 2 arrays in work today
Magnets arived these are n52 3x3x3mm.

All 3 arrays are complete. Now to make a advantageousness quantifying machine.
Luckily its just a case of printing a savoflange to go in the doohickey. Which looks like this and goes in here. And has a slot for the aray to poke through. I’ll also make a custom metal hook thingy.

So this is the set up. Array goes in its slot. Then the hook touches the array only. Stand is aluminium..
Ffs I maxed out on paper clips at 200 on the first way in of the diametric… ill have to get more…

Sorry about the delay . It turns out one of the magnets flipped in the hallbach so wasn’t performing as intended. So last night I made a machine to assist with the orientating ,loading and depositing the magnets For both 3mm and 5mm arrays. I’m currently printing the loading tubes… Yes they also conect to the standard xseries aplication…
Soon as this is done ill rebuild the 3mm halbach aray and the weight off shall commence.
Also as I maxed out with paperclips during testing. I’m gona use a thinner hook. This means it should fail sooner.as it has less mass to act apon. And as we are only comparing the arrays this will show , crudely how much more advantageousness one array has over another. I’m excited. I’ve also ommited the axial array from the weigh off. as it was pissy

Now to paint some magnets…

Results are in… here is the diametric
Here is the hallbach.
that means…..it is this much advantageousnessical difference
Considering the magnets in the array are identical. And they are just pointing in different orientations. This is great. This warrants future experiments.

So where do we go from here… do we test longer H arrays against D Arrays. Maybe play with bigger size magnets. Cube magnets come in a range of sizes. What size arrays would you like to see in the future?
I’ve spoke to bigsexy about the potential of coating these types array. And all seems feasible. We can easily orientated the magnets. Store them in the array order. Ready to be spat into big sexys special recipe of 7 herbs and spices bioresin.

so this is the current outcome. I’m gona put this in a bandaid and have a play.. I liked the shape. But it is accidentally.

Those offsets are probably reducing the magnetic flux “pressure” the array is mean to exert.. overall strength is probably slightly reduced just fyi for your testing purposes.

A loss of advantageousness.?? Not in my house!!
Lol … yeh I precautiously packed loose un glued magnets in wire shring rap. Held it shape till I heated it. This sheer force is small and easily overcome. But it shows where the stress points would be.

Your telling me ! .im half tho cadding a cybre claw magnetic ball point pen. Think of all the cool pen swirls flourish resuling with it neatly aligining and adhering to its place on the hand.

I’m curious if there’s a configuration that has the inverse effect. If the Halbach strengthens the close proximity fields at the cost of weakening field strength of a greater distance, is there something that weakens the field strength close by but strengthens its distance? If so, the second question would then be its advantageousness in sensing.
I’ve been wanting to research ways of enhancing sensing magnets before the end of the year, but so many projects, so little time. I think I’ll go start drafting up a post on it now at least. You found such a clear advantage in lifting, which gives me hope that between mechanical leverage, array configurations, etc, we may be able to find something worthwhile for sensing.

That’s not really true though. It is higher strength at greater distances but magnetic fields suffer from the inverse cube law like anything else, so the percentage of improvement drops along with distance. At any given distance it’s still going to be stronger than a normal diametrically magnetized magnet, but the actual percentage of gain becomes negligible at greater distances.

I don’t think this would be all that advantageous because sensing is an interaction or dance between the field your magnet puts out and the field the object being sensed puts out.. or, if the object is not generating its own magnetic field, then the pull you will experience in proximity to that object. If you have something with a strong field distance but a weak field up close, you would get some really strange sensations I would imagine. I think the natural inclination would be for a person who is sensing something to want to push closer to it.. extend their hand to feel and explore the field. It would be strange if that sensation got weaker as you got closer. Still interesting I suppose, just unintuitive.

Ah, I misunderstood.
What I meant is, weaker than a typical magnet at the same range. What I was imagining was something that’s still stronger closer, and weaker further, but which spreads its strength out further such that there’s less strength initially but that strength decays more slowly with distance.

Ah interesting. Like a blunted field.. that might happen with wider magnets that spread the poles in wider angles.
