Abstract
A device for measuring complex permeabilities, called a magnetic flux sensor, has been constructed from ferrite. Tests of the sensor which involve the imaginary part of the complex permeability are described in this paper. With a signal‐to‐null ratio of 2:1, the sensor can detect a change of resistance per unit resistance in metallic samples of 1.1×10−7, an electrical power absorption of 3.4×10−10 W, a radiant flux of 3.1×10−8 W/cm2, and a temperature change of 4.9×10−5°K. Construction of the sensor is also described.Keywords
