Embodiments of sensor devices for characterizing magnetic fields formed in substrate processing systems and methods of use thereof are provided herein. In some embodiments, an apparatus for characterizing a magnetic field in a substrate processing system may include a carrier having a form substantially similar to a substrate to be processed in the substrate processing system. One or more magnetic sensors are disposed on the carrier for measuring a magnitude of a magnetic field formed in the processing system in an x-, y-, and z-direction. A microprocessor is coupled to the one or more magnetic sensors to sample data representative of the magnitude of the magnetic field in the x-, y-, and z-directions proximate a position of each sensor. A memory device is coupled to the microprocessor for storing the sampled data. A power source is provided to supply power to each magnetic sensor and the microprocessor.
