摘要

This paper presents the design, fabrication and validation of the single layer planar search coil along with its integration with developed magnetic field measurement software (FPGA driven) using Moku:Go. The developed device is capable of measuring an unknown magnetic field without prior knowledge of its frequency. It can also measure and display the frequency of the magnetic field. The developed device is validated in measuring AC magnetic field range from 1 milligauss-2000 milligauss (100nT–200µT) over frequency range 50 Hz–60 kHz with sensitivity varying from 1 µV/mG (at 50 Hz) to 0.93 mV/mG (at 60 kHz). The performance of developed device has been compared with the commercial magnetometer and results show remarkable closeness with maximum relative error of 5.33%. The developed magnetometer is an affordable solution for measuring time varying magnetic field in EMI/EMC compliance testing, measurement of safe limit of electromagnetic exposure for human beings (as per ICNIRP guidelines).
