Suppose a magnetic field is unidirectional in the $\mathrm{z}$ direction in a region where the current density is uniform and flows in the +y direction. The field magnitude in such a region depends on $x$.

Question

According to Ampère's Law, if the current density is uniform and flows in a specific direction (in this case, the +y direction), and the magnetic field is unidirectional (in the z direction), the magnetic field's magnitude would not depend on the position (x) in the region, assuming the medium is homogeneous and isotropic.
