Abstract
The possibilities for determining the distance to a ferromagnetic object with unknown magnetic characteristics by the measurement of its magnetic field at two spatial points are considered. An unconventional measurement device, which allows us to determine the distance to an object in real time, as well as an algorithm and software for the processing of measurement results with the computer-generated visualization of the parameters of a magnetic field induced by an object, were developed. The error in determining the distance to a sought object does not exceed 20.0%.
