A four-transistor circuit is described for a battery operated magnetometer that has 0.1γ resolution using 1-in diameter 4-79 or 6-81 Mo-Permalloy tape cores of 20-40 Mx capacity. The center-tapped drive winding also serves as the sense winding, simplifying the sensor assembly. Some signal-to-noise results are presented to illustrate the fairly wide difference that may exist between cores of the same cross section and to demonstrate the advantage of reducing core area.
