Yet another Planar Magnetic Line Source, the SMAPPP

[solhaga]

So here's the chart over the force on a aluminium foil conduit in a magnetic flux density produced in a push pull configuration when it moves from rest level to 1 mm above rest level:

Enlarge it or open the picture in another tab to view it better.

So if only the deviation in percent from the rest level manifests in distortion, there's a clear winner.

I thought that I would have gotten my new cutting machine (Silhouette Cameo 5) by know, but it will still be a while.

So I almost finished the rest, in CAD at least.

Here's one of 44 steel plates, 184 mm wide and 200 mm high.
22 magnets, 10x5x3 mm, will be mounted on each steel plate.

A nut bar will hold front and back plates together in three places:

En mutterlist skall hålla samman fram- respektive bakplåt på tre ställen:

A front plate is fastened with a long screw in the nut in te bar. On the protruding rest of the screw, the back plate will be fastened with yet another nut.
Look at the vertical screw holes in the plate above.
The back plate must be wiggled in place.
I will probably not use all screw holes.
The nut bar has also screw holes for supporting side beam.

Here's an attempt to visualize it:
