Hall magnetometer with enhanced resolving power and its application

The instrument is intended for mesuring the stationary magnetic fields up to 5 T and their inhomogeneities. It consists of two measuring channels, one gradient channel and that one for registration of deviation of a value measured relative to the reference signal. The result registration is performed via the external digital voltmeter with approximately 0.01% error. Magnetometer resolving power for relative and gradient measurements in the superconducting solenoid with a ''frozen'' magnetic field is as high as 10-5 T in the field up to 5 T. The way of measuring the direction of magnetic field is realized with angular accuracy better than one minute using one Hall transducer
