Hello,
I am trying to create a stationary magnet within the Magnetic and Electric Fields setting. I have tried using Ampere's Law and Current Conservation for each pole of the magnet, but keep getting a singular matrix error.
I have seen lots of examples of how to create magnets in the (MF) setting, but I can't figure out how to create it in (MEF).
Any recommendations would be greatly appreciated!
Thanks, Tesla

I've attached an example, using the MEF formulation per your request. I don't claim that this is a great model per se, but it doesn't give any computational errors! So take a look at it. FYI, I chose the source of the magnet's field to be a bulk magnetization (rather than try to specify poles). By the way, if you have air or empty space in your problem, be sure to assign it a small but non-zero electrical conductivity!
