A resumé is given of the basic relations between the magnetic characteristics of the core of a coil and the inductance and resistance of the coil as measured on an alternating current bridge. Modifications of the simple relations to take account of the interactions of eddy currents and hysteresis in the core material are developed, and are seen to require a more complicated interpretation of the data in order to obtain an accurate separation of the eddy current, hysteresis, and “residual” losses. Means are described of minimizing or eliminating the disturbing effects of distributed capacitance, leakance and eddy current loss in the coil windings. Essential details of the alternating current bridge and associated apparatus, and of the core structure, are given.
