ABSTRACT:
A method of, and apparatus for, the detection of magnetization of a magnetic circuit, especially for the detection of a current flow interlinked with the magnetic circuit, wherein a timed or temporal cyclic magnetic flux change is generated by means of a detection-current flow used for detection purposes and interlinked with the magnetic circuit and a detection signal is formed as a function of time intervals dependent upon the magnetization.
