The magnetic field distribution within a square spiral inductor is investigated in this paper by summing closed‐form expressions for the fields from each segment. Plots illustrating the variation of the normally directed B ‐field penetrating the surface of the spiral traces are then developed for a variety of perspectives. The expressions and insight gained represent an essential step in developing a detailed model of effects such as current crowding, which significantly limit the spiral's performance in practical circuits.
