Pulse Coil Design Simulation

[mikedmonds]

Dear Forum,

 

I need a simulation program that could be used to optimize the free air flux distribution of a pulse coil (capacitive discharge). I would like to change parameters and see a plot of flux lines around the coil, and be able to determine Gauss levels at different points.

 

Does anyone know of anything that will do this?

 

Thank you very much!

 

Sincerely,

Mike

That maybe ?

You still haven't told for what OS nor at what price.

 

If you wish a uniform induction, old Helmholtz did a good job with his coils. They can be a starting point to added compensation coils. Often, coil resistance isn't a worry at capacitive discharge, since magnetic energy is the limit.

 

Also, the induction from a single loop can be reasonable computed in 3D, so any coil form with cylindrical symmetry results in a field that a spreadsheet can compute - no special software then.

 

What induction are you seeking? Up to some 10T you have still some freedom about the coil's shape, but at 50T (is the record still at 200T?) mechanical stability imposes everything. At 7T I used copper foil, as broad as the coil's length, wound spirally and insulated with paper, hold in a hole in plywood - but epoxy would improve, with glass fabric as an insulator. Thick aramide fabric would hold the metal in place at higher induction.
