Original Abstract

The paper deals about result measurement for designed apparatus 3D Teslameter magnetic field. This apparatus allows measure direct or alternating magnetic field in environment with strong electromagnetic disturbance. In the case of measure alternating magnetic field is possible measure signal with lower amplitude than electromagnetic disturbance, concrete S/N <0.01. The measurement was performing in workplace for mapping magnetic field. In the designed 3D magnetic field meter, Hall probes are used for the measurement of magnetic flux density; also, the influence of Earths magnetic field is compensated. The measurement result was compared with simulation results in program MATLAB. In this paper are discussing differences between measurement and simulation results and determine source systematic error. The magnetic field map is measured using the calibration 3D meter and is used for the reconstruction of material properties of the measured sample.
