FIELD: measuring techniques.
SUBSTANCE: method includes determining value of critical current without penetration of superconductor by solenoid magnetic field on basis of difference of fields of solenoid without superconductor ring and with it, as well as by fact that in measuring device magnetic core is magnetically enclosed and has space at portion inside solenoid, in which field sensor is placed, and superconductor ring is placed on solenoid at level of field sensor.
EFFECT: higher precision, higher trustworthiness.
