1. A system for controlling a magnetic field strength, the system comprising:
- a magnetic field generator for generating a magnetic field for receipt by a responsive device, wherein the responsive device comprises a tire monitor device; and
a controller in communication with the magnetic field generator for determining a strength of the magnetic field and generating a control signal operative to adjust the strength of the magnetic field to a level sufficient for use in controlling the responsive device, wherein the magnetic field generator comprises a driver circuit and the control signal is operative to adjust the magnetic field strength to the level sufficient for use in controlling the responsive device by incrementally increasing the magnetic field until the responsive device responds.
