Actually I don't think it is magnetic but sensitive to things that conduct electricity (metal in particular). It measures induction. I find if I can get my rims over the wires they trigger almost all lights. (bet you didn't know there were theramins all over town in the pavement huh? They should put a speaker next to the lane so as the pitch rose you knew you were on the sensor
).
