Abstract :
This paper covers the theory and design of an instrument which measures, with the aid of an oscilloscope, the differential permeability of toroidal cores used in magnetic amplifiers. Additions and modifications are discussed which adapt the instrument for rapid selection of cores for production use, using a meter for an indicator. An important feature of the device is that all measurements are made before wire windings are placed on the cores.
