Introduction：
The FESP 5133-1330 is a hand-held radiating loop antenna test set manufactured by Schwarzbeck (Germany) and distributed by EUTTEST. It is designed for magnetic field immunity testing at a test frequency of 20 kHz, with a fixed test distance of 50 mm between the center of the coil and the surface of the EUT, and generates a magnetic field strength proportional to the coil current. Typical application is to meet the requirements of the test standard VG 95377 - SF 01 G for magnetic field immunity testing.

Distribution of the strength of the generated magnetic field is plotted:
The figure below shows the distribution of magnetic field strengths in the cross-sectional plane of the 5133-1330 loop antenna. At this point the coil current is set to 1A and the results on the right are shown in percentile of the maximum field strength generated in the inner region of the coil. The two axes x and r in the plot are highlighted in green and red, respectively, and the magnetic field flux is analyzed along these x and r axes.
