Abstract
A four-transistor circuit is described for a battery-operated magnetometer that has 0.1 γ resolution using t-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.
