MAGNETIC CHARACTERISTIC MEASURING INSTRUMENT, MAGNETIC CHARACTERISTIC MEASURING SYSTEM, AND METHOD OF MEASURING MAGNETIC CHARACTERISTIC

摘要

PROBLEM TO BE SOLVED: To make it possible to measure the AC magnetic characteristic of a soft magnetic material in a high magnetic field.;SOLUTION: A magnetic characteristic measuring instrument 100 includes a second primary coil N_1A separately from a first primary coil N_1O. The second primary coil N_1A is arranged outward of the first primary coil N_1O, with a space from the first primary coil N_1O, almost coaxially with the first primary coil N_1O, in such a way that the directions of magnetic fields generated by currents flowing in the first primary coil N_1O and second primary coil N_1A become the same at the same time of day.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
