Each embodiment (10, 110 and 210) includes a magnetic element (12, 112 and 212) producing a magnetic field. In the first embodiment (10) of FIG. 1, the magnetic element (12) comprises a magnetic bit strip disposed extending in a circular arc on a fixed or stationary plate (14). In the second embodiment (110) of FIG. 2, the magnetic element (112) comprises a magnetic bit strip supported on a movable bar or rod (114). In the third embodiment (210) of FIG. 3, the magnetic element (212) comprises a magnetic bit strip disposed in a rectilinear path on a stationary plate (214). An electrical resistor (16, 116 and 216) is included for changing in electrical resistance in response to changes in the magnetic field produced by the magnetic element (12, 112 and 212). The resistor (16, 116 and 216) comprises a giant magnetoresistive sensor. A voltage sensor (18, 118 and 218) is included for sensing the voltage across the electrical resistor (16, 116 and 216), the sensors (18, 118 and 218) being connected to the resistors (16, 116 and 216) by electrical lead wires.
