hello
I want to calculate the magnetic field (Hz) of the loop circular
the power sapply is a Vsin source
please help me

Hi
first of all, your +air box is very small, I would rather propose to use a sphere, several times bigger than the coil, as magnetic field fills in quite a volume, and would else be strongly influenced by the limited volume you have defined
then for your coil, having current appearing in thin air lik that is not very "physical", I would rather define a circular current density (use a cylindrical coordinate frame, and have a full coil loop
In anycase with you approach, I would have set one face to the GND and the other to the voltage source, just to fix the "0" V, else your equations are "floating" you are missing a reference, which is not really a problem for MF as you do not solve for V, but that could be the case for MEF if you image to use that physics

Good luck
