The current decreases, in a first approximation, as a cosinusoid, ending
at an angle smaller than 90 degrees at the terminal. Not an
exponential. In a coil with a significant terminal the currents at the
bottom and at the top are not so different. Maybe the current at the
top is 50% of the current at the bottom.
