Measurement of Magnetic Field Generated by Wireless Chargers

The article concerns the issues of electromagnetic compatibility of wireless chargers designed to charge electronic devices. Its purpose is to present an exemplary application of the laboratory stand and measurement methodology for measuring the level of magnetic induction of interference in the frequency range from 100 Hz to 100 kHz, generated by wireless chargers intended for charging electronic devices. The developed method of measuring magnetic induction was presented and the set up measurement station based on the measuring equipment being the equipment of LAB-KEM WEL WAT was described. The article also presents the results of measurements for selected wireless chargers intended for charging electronic devices, which were used to assess the magnetic induction value and compare wireless chargers in this respect.
