I want to simulate and see magnetic field variations inside a ring magnet.
But whenever I place a STL model with air inside the cavity of the ring magnet, I don’t see any magnetic field value using statistics feature in post-processing.
I have to use magnetic disc or any conductive solid with permanent magnet of same magnitude inside the cavity of the ring magnet to visualize any magnetic field changes. Please help!!
I see that you have selected only one solid closed body as a coil, and the coil must be divided into 2 parts to be correctly assigned in the simulation. So that being the problem, the solution is just doing a CAD preparation at first, dividing your coil by 2, as simple as that. To know more on how is an usual electromagnetic setup with a divided coil, please take a close look at this page, and try to compare the setup of the tutorial with yours to use it as a guide.
