FIELD: measuring equipment, possible use for registration of ultra-low frequency variations of electromagnetic fields.
SUBSTANCE: for solving the problem, magnetometer sensor includes sensitive element, made in form of rod connected to base, with magnetic element rigidly held thereon, optical system, consisting of optically connected light radiation source, mirror, held on magnetic element of sensitive element, and light radiation receiver. Control block is electrically connected to source and receiver and light radiation. Lower end of rod of sensitive element is connected to base in jointed manner. Sensor of magnetometer is provided with actuator, which is made in form of piezo-engine of linear movements.
EFFECT: increased sensitivity with simultaneous increase in resistance to dynamic overloads of magnetometer sensor.
