Abstract: (2009 Views)
Atomic magnetometers have found widespread applications in precise measurement of Earth’s magnetic field due to their high sensitivity. In theses measurements, various methods have been utilized to compensate the Earth’s magnetic field. In this paper, a method based on finding the minimum magnetic field by producing the opposite field through three pairs of Helmholtz coils and minimizing resonance frequency of the atomic magnetometer, has been proposed. Using this method, the exact value of Earth magnetic field vector is obtained as 35.132 with a sensitivity of 2 nT.
