In addition to this being off topic, most users here wouldn't be able to help you. You are talking about an actual scientific research application that would be much more complex to handle than what most people here are used to.

I do have some experience with FEA in general myself but do not currently have the time to do all the background reading necessary to help you (I am not familiar with FEMM). By FEMM, I am assuming you mean this, the first search result returned by Google.

It would probably be better to ask this question on a Stack Exchange site. I am not sure which one would be best for your question. There are sites for code writing/review, engineering, and physics. All of which could potentially be relevant. If you post on one of those sites, be sure to link to the site for FEMM as they will need to know specifically which library you are using in order to help.
