Infolytica MagNet v6 coil definition problem

[orphefs]

Hi everyone,

I am using Infolytica Magnet v6 to simulate magnetic fields, more specifically the flux density of a circular coil of rectangular cross-section that is excited by a current source. I have posted an image of my design below:



The copper-coloured part is the coil, which carries the current.

I created this body using SolidWorks 2010. I created the cylinder, then I cut it along the axis of symmetry, then I mirrored it, so that I get two entities for the coil altogether. The reason I did this is the following: when defining coils, MagNet requires the assignment of surfaces current flows in and out of.

I am having the following problem: I am not sure which coil definition to use, should it be a 2-terminal or 4-terminal coil? I have looked at tutorials and I havent found the answer...

Here is an print screen of the flux density on the surface of the coil (blue colour = 0 Tesla). It seems that the current is confined at the internal faces of the coil entities, it definitely does not look right to me.. I got this by defining a 2-terminal coil from the 2 lower back-to-back faces of the two bodies of the coil. By defining a 4-terminal coil from all 4 back-to-back faces, I get a similar flux density pattern, it is just the same density mirrored at the top of the coil, where the other two boundaries are..



If anyone is familiar with coil assignment in Infolytica MagNet, I would be very very grateful if they could post an answer to this! Looking forward to any replies,

Kind regards,
Orpheus
