If the current is constant over space but not time you can still bring it out of the integral in the BSL. So this just means the field will also vary with time, but still be proportional to the current at any instant in time. – BioPhysicist. Aug 20, 2024 at 0:53. @AaronStevens Perhaps my wording was off.

WebThere is no magnetic field associated with a simple stationary charge. So this really means that you cant have magnetic field being proportional to an electric field. Another simple case - a line of equally spaced positive charges moving along. This is a current. Here the magnetic field depends on ( is proportional to) the current.
