PDE magnetostatic electromagnet how to measure the magnetic field.

Hi dear support from Matlab.
I recently finished designing my step/stl file on an electromagnet.
I got the shape, how do I apply around the electromagnet a coil? Or is this not needed? I would like to know the magnet field between two poles in 3D. Second why do I need boundary conditions?. The whole nabla thing is new to me.
For what I understand is, I upload the stl file in to Matlab, somehow apply the Ampere windings, and permeability for the stl file component. and do a simulation to determine the magnetic field. Maybe also change the geometry of the magnetic poles to increase the amount of Tesla.
I build something from scratch, heat treated (permeability 15000-20000) it and applied 6A at 30V over 500 windings from 0.4mm insulated wire.

It might be easier if you do a 2-D approximate analysis. For 3-D, modeling the air around the coil to solve for magnetic field can get very complicated if you are unfamiliar with FEA workflow, particularly dealing with mesh. On the other hand, you can draw simple 2-D geometry using PDEModeler, where you can complete the whole setup for magnetostatics analysis or create geometry using decsg function and use PDEModel object workflow.
