A magnetic field measuring system is disclosed. The magnetic field measuring system includes a substrate, a conductive well formed in the substrate, the well having a first side with a first length, a first contact electrically coupled to the conductive well at a first location of the first side, a second contact electrically coupled to the conductive well at a second location of the first side, wherein the distance between the first location and the second location is less than the first length, a stimulus circuit coupled to the first contact and the second contact, and a sensor for identifying a property indicative of the length of a current path from the first location to the second location through the conductive well.
