The measurement of vehicle magnetic moments and the results from use of a fluxgate magnetic sensor to actuate a lighting system from the magnetic fields of passing vehicles is reported. A typical U.S. automobile has a magnetic moment of about 200 A-m2(Ampere-meters2), while for a school bus it is about 2000 A-m2. When the vehicle is modeled as an ideal magnetic dipole with a moment of 200 A-m2, the predicted results from an analysis of the sensor-vehicle geometry agree closely with observations of the system response to automobiles.
