Abstract: A measuring device for determining magnetic properties of a magnetizable test specimen comprises a measuring coil winding which passes around a magnetizable measuring coil core. The measuring coil core comprises magnetic flux passage faces arranged at a distance from one another. The test specimen is arranged adjacently to the magnetic flux passage faces. A high-current pulse through the measuring coil winding causes a magnetic flux through the measuring coil core and the test specimen. A temporal profile of electrical characteristic variables of the measuring coil winding is detected using a sensor device. The electrical characteristic variables of the measuring coil winding detected by the sensor device are set in a ratio to additionally ascertained electrical characteristic variables of the measuring coil winding without the test specimen. A magnetic property of the test specimen is determined from the ratio of the electrical characteristic variables to one another.

Abstract: Determining the inductance L of an electrical component includes a high current pulse being generated and conducted through the electrical component. The electronic component is arranged in an electrical resonant circuit, in series with a reference component and with at least one capacitor. The resonant circuit is excited to oscillate by the high current pulse. Electrical properties of the electrical component are measured for a measuring duration, and the inductance L of the electrical component is determined from the measured electrical properties. A voltage drop U across the electrical component and a reference voltage drop UR across the reference component having a known reference inductance LR is measured. The inductance L of the electrical component is calculated as a product of the reference inductance LR with a proportionality factor, which is dependent on the measured voltage drop U and the measured reference voltage drop UR.
