      Once they are in an array like this and shielded somewhat by the material that encases them, the attractive force between the two arrays at any significant distance is very low. The whole idea with this type of array is to concentrate the field towards the center, so that doesn't leave a lot of the field for the outside.

    Electric motor's speed to torque ratio depends on its inductance, stronger magnetic field helps shift this ratio towards smaller RPM and higher torque, power is unchanged. With low RPM motor you need less (or none) gearing, so total drivetrain efficiency is higher, but the downside is that the shafts and the windings armature need to be made tougher and bulkier to handle all that torque.

      This is because the imperial system is so garbage and outdated it doesnt even include measures near this small so we kind of have to use millimeters, and we use centimeters a lot too. All arbitrary in the end though

    right hand rule / 90 turn and only two face the same way. Try using two apposing bowlshaped magnets with their bottom of the bowl facing eachother. In the center you'll find some interesting effects on the center edge and surrounding area. Try surrounding that setup with some non magnetized steel bearings and then see how they behave inside and outside the center point.

But most other magnets can be cut with not problem if you use the correct blade type (abrasive for ceramics) and plenty of cutting oil.

    The number of magnets is directly proportional to the field strength, Tesla. Increasing the number of sides to a Halbach, you can increase the number of magnets. Using 3D printing of metallic solutions, you can make intensely small magnets under magnetic fields during the curing process. You could make extremely strong magnets then. +1000 Tesla at low cost with a high capacity output. If you look the first set of 4 magnets(Top, Bottom, Left, Right and then rotate right to the next set of 4) you can see the magnetic fields form an infinity with a 90 Degree angle of incidence at center; The second set of magnets(Top, Bottom, Left, Right) have a zero degree angle of incidence at the center. This is in reference to the last example in the video, there are 2 sets of magnets with 4 in each group.

      A ringlight with twenty LEDs makes twenty glowing stripes. (Rotate the ringlight, and the stripe-pattern rotates too.) "Ferrocell" isn't showing magnetic field lines, instead it's showing LED reflections from microscopic strings of particles in ferrofluid. It's much like illuminating some iron filings with a lighting strip full of separate LEDs. Yes, the iron filings will produce glowing reflections, but the stripes of light-reflection aren't "field lines." The actual micro-pattern of iron particles WOULD show the magnetic field shape. But all we can see is the optical "glints" or "highlights" caused by the curved strings of reflective microparticles. (It's much like the glistening highlights of shiny hair. We want to see the actual hair patterns, rather than only the curved glowing reflective highlights caused by the hair.)

      Sorry. Any mass, irrespective of its' shape, will generate its' own gravitational tensor. To date, that's a known characteristic of not only barionic mass but dark matter as well.

    I thought the Halbach array for the electric DC motors was stacked both as layers and as in relation to the next reducing the cogging effect as well as making one side of the magnetic field strength stronger, the other side not necessarily weaker but more “pancaked” out (Changes the shape of the field). The goal of producing a stronger field whether inward or out depending on the other component of an electric motor. (Either can be the stator or the rotor) . I tried to attach a drawing to show what I am attempting to say.

    I know of FOUR ways to make motors or straight rails POWERED by the magnets themselves...at least two are patented, but one uses weak, custom made ceramic magnets, one is big and complicated, the other barely keeps itself moving, and the one I invented I only got a couple prototypes working enough to know it works, probably better than those, because its simpler.
    I'd love to show the whole world how to build it, if I just had the means to make some custom metal parts like these!
    I need maybe a couple dozen thin, flat magnets, and some simple metal parts, made of certain common metals like iron or aluminum or copper. Either I'll make it myself when I get the tools again, or someone will work with me, live streaming online perhaps so everyone can see, and we can make one!
    Then we can make this simple mechanical levitation device I'm quite sure will also work, which could eliminate the need for propellers and rocket engines if it works! (Its so simple I'm sure it will work too, and I'm sure mine will spin really fast and put out a lot of power when I build a better one, with precision parts, instead of hot glue!)

      He talkedfast. Wasn't it bending or rolling the adjacent field? The neighbor magnets push the field out and physically withstand a lot of physical pushback to hold it further out. Magnets only add field effects, they do not cancel. So if the North field is pushed out, the South field is pulled in with it.
