Kevin said, "a magnetic field is created as an electric field changes,
and an electric field is created as a magnetic field changes".

I thought a magnetic field is proportional to the current, not the
change in current. Whereas an induced current is proportional to the
rate of change of magnetic field. That's the assymetry I refered to,
but I'm seeking clarification. Am I wrong or are we both right?
