The paper presents the possibility of using a Sagnac optical circuit with a 3^3 divider as an optical magnetometer, as well as interference interactions in a 3^3 fiber-optic divider in the optical circuit of a magnetometer on SPUN fiber. The field applied to the sensitive region of the SPUN fiber circuit makes it possible to control the Sagnac phase, and, therefore, knowing the Sagnac phase, one can judge the magnitude of the applied magnetic field. This design of the magnetometer makes it possible not to use Faraday mirrors, which makes it possible to use the magnetometer under more severe conditions.
