Zusammenfassung:	PROBLEM TO BE SOLVED: To measure alternating current loss of a superconductive wire easily with high accuracy using a simple device. SOLUTION: A superconductive magnet 1, a sample coil 3 and a magnetic field detecting coil 2 are coaxially arranged. A current is applied to the superconductive magnet 1 to generate the external magnetic field, and a voltage signal of the sample coil 3 is detected by signal measuring equipment 4 from a main detection coil terminal 6. At the same time, a voltage signal of the magnetic field detecting coil 2 is detected by the signal measuring equipment 4 from a signal line 2a. These input signals are outputted to a computer 5, where data processing is applied to obtain the alternating current loss value.
