Abstract

FIELD: magnetic measurements, applicable for measurement of static, variable and pulsating magnetic fields with a high accuracy. SUBSTANCE: the method consists in excitation of magnetic resonance in a ferromagnetic core by a variable field at a frequency equal to the resonance frequency in a static field with an induction exceeding the saturation induction of the core; a resonance curve is obtained, a static field is modulated at a frequency lower than the resonance frequency, a derivative of the resonance curve is obtained, the resonance frequency is measured, and the magnitude of the static field is found by formula B= kf. Variable and pulsating fields are measured depending on permeability of the core in the magnetic field, and the field magnitude is found by formula B= kU. EFFECT: enhanced accuracy.

Изобретение относится к магнитным измерениям и может быть использовано для измерения постоянного, переменного и импульсного магнитных полей с высокой точностью. Способ заключается в возбуждении магнитного резонанса в ферромагнитном сердечнике переменным полем с частотой, равной частоте резонанса в постоянном поле с индукцией, превышающей индукцию насыщения сердечника, получают резонансную кривую, модулируют постоянное поле с частотой ниже резонансной частоты, получают производную кривой резонанса, измеряют частоту резонанса и находят значение постоянного поля по формуле B1 = k1•fo. Измерение переменного и импульсного поля осуществляется по зависимости проницаемости сердечника в магнитном поле, а значение поля находят по формуле B2 = k2•U.The invention relates to magnetic measurements and can be used to measure constant, variable and pulsed magnetic fields with high accuracy. The method consists in exciting magnetic resonance in a ferromagnetic core with an alternating field with a frequency equal to the resonance frequency in a constant field with an induction greater than the core saturation induction, obtain a resonance curve, modulate a constant field with a frequency below the resonance frequency, obtain a derivative of the resonance curve, measure the resonance frequency and find the value of the constant field according to the formula B 1 = k 1 • f o . The measurement of the alternating and pulsed fields is carried out according to the dependence of the permeability of the core in a magnetic field, and the field value is found by the formula B 2 = k 2 • U.
