Magrid design.

Postby Torulf2 » Fri Mar 01, 2013 2:38 am

How about this magrid design? Have it been something like this before?
Its a twisted circle, its have two gaps and the magnet lines are closed.

Looks like it would have one hellaciously long line cusp. They tend to leak badly.

You can think of this as a descendent of the "baseball seam" devices from the 70s. See: http://www.flickr.com/photos/llnl/3085193876/

2 very long line cusps, but yes leaky.

Nice graphic, Torulf.
But, if it breaks, will it leak mercury? :)

Long line cusps but narrower. It is a partiial solution and I suspect is approaching what I have considered and what I suspect is the Skunk works design. A key point is forming a single central magnetic null that might lend itself to Wiffleball inflation.

Also, I'm uncertain what the B field is like where the magnet reverses direction. The discussion of the baseball lacing design deficiencies discussed in the EMC2 patent application may indeed apply.

Why do you think these would be narrower? They are basically just the typical point cusps stretched all the way around the sphere several times.
