I have tried modifying the length of the wire, magnetic flux should remain the same, but it isn´t. It seems the longer wire produces more flux at 1mm (it makes no sense). On the other hand, I do not understan why this shape in the magnetic flux, it should be purely circular.

Thanks a lot for your reply. This is one of the things that I supossed in the beggining, but I made the boundary sphere wider and the result is the same (see attached). It seems the magnetic flux shown in the boundary layer is debt to the sphere is very small. Any other idea?

Sure! I attach them here. Thanks a lot! First one is the 3D model (lateral view), showing the value of the magnetic flux density in COMSOL 5.5 (this value do not matches with theoretical) The second one is 2D in COMSOL 3.5, this value really matches with theoretical

Hello, I have used an edge current of 10 A through a 0,45 cm (lenght) wire inside an air sphere. The thing is that, according with Ampere law, the magnetic field (B) produced at a 1 mm of distance from the wire shall be 0,002 T, and I am obtaining much higher values in this simulation (around...
