FIELD: measurement of magnetic field induction produced by a movable object at the background of interferences of a direct current electric traction line.
SUBSTANCE: the method consists in the fact that the component of increment of the line magnetic field induction is measured near the line, and the components of the induction difference between the measuring and compensation transducers at the remote movable object are synchronously measured, coefficients of proportionality between each difference component and the increment component are found, then the respective current value of the increment component multiplied by respective coefficient of proportionality is subtracted.
EFFECT: provided compensation of non-uniform interferences of lines at measurement of the fields of a movable object at a distance of 500 m and further.
