in the second graphic displayed, why does the larger left array group have an array that is completely green whereas the others have red area of ?flux density?
Also, the connecting area of the 2 groups seems to have the most concentrated area of red while the end of the right array group has sparse red flecks?
Thanks for posting though!
You're making it easier for me to visualize magnetics!
The green centerline on the left group is actually the center gap and has a slightly lower density than the yellow, orange & red. The second map is linear while the third is logarithmic. I will upload the hires gifs and PM you the link. Keep in mind that this is cross section showing 'internal' and 'external' flux. Also remember that flux rarely follows a straight line even inside the magnet.
Anyone familiar with Vizimag will be aware that this a cross section slice of cylindrical magnets straight through the centerline diameter. Looking at the far right you will see the flux density that exists across the top and bottom of the layer, simply revolve them around each set. This clearly shows the shortest path is directly between the rows to the opposite pole and does not radiate outward as we see with the large array to the left. It is this concentration that traps the roller.
For who? I am not bagging this guy, i love the fact someone is trying to help, but realistically, those field patterns are not out each end, they run over the top, same as electrical currents, shortest route to the other end, so it would be hard in 2D, what i am saying is the special effect gause pattern from overhead would be wider on the sides than at each end, and those end patterns would actually be overhead or orbital if suspended. I love that exx shows so many variations to help teach it.
there would be more on the sides where the poles are, in any event it would look vastly different with the roller on top of it, which is the purpose of understanding this field. But hey what would I know about the Mayernik Array. Nice effects though
Since the flux paths are quite direct between the magnet rows in free air, the only thing adding a roller to the top would do is provide a cleaner path for the flux. The diagram would not change much since the flux is already following that path. ;)
Interesting software, but I'm not familiar with what Vizimag is showing me here, or that the flux path representation is correct (the "unfluxed" mags in the middle of the 3 mag array track) as it doesn't mirror what I feel when cradling a roller mag over the array.
Resistance to sideways movement remains constant when trying to force the roller mag off the side of the array as does the attraction down and never ahead.
The flux is there on those mags. If you look closely you will see that it routes in the gap between. If you look at the last magnet set to the right you will see the pattern that exists above the table and below the table. But the flux squeezes into the gap between the rows. Vizimag is 2D and doesn't really show us everything we need. I wish he would let us step the centerline and generate MRI like slices at least. I do not think the flux is singular around each row, but it merges across.
Where can I get this software?

I'll send you a PM as You-tube makes it very difficult to post links ;-)

Plexi is the tool used to convert the effect. ;)
