Magnetic field control provides a valuable method for manipulating atomic energy levels and interactions in quantum precision measurements during the interaction between atoms and light. In high-precision quantum sensing experiments, precise measurement cannot be achieved without the cooperation between magnetic field systems and optical detection systems. In order to meet the magnetic field requirements of different optical detection systems, a set of fast switching magnetic field systems and alternating magnetic field systems were developed, and this device was combined with Lee-Whiting coils to achieve kHz alternating magnetic field signals. In the experiment, the frequency adjustment of the alternating magnetic field can be achieved by adjusting the size of the inductance and capacitance components, as well as increasing the adjustable range of the components to expand the frequency spectrum of the alternating magnetic field. The experimental results have demonstrated the feasibility of this method in generating alternating magnetic fields, which can be used for the study of cold atomic absorption spectroscopy under alternating magnetic fields.
