Abstract
Provided are a biomagnetic measuring device and a control method for a biomagnetic measuring device that can measure biomagnetism more accurately. A biomagnetic measuring device according to the present invention includes: a first magnetic sensor and a second magnetic sensor that each include a cell having an internal space, and detect biomagnetism utilizing an optical pumping action by plasma generated in the cell; a plasma generator that supplies electric power for generating plasma in the internal space of each of the cells included in the first magnetic sensor and the second magnetic sensor; and a power supply controller that controls the plasma generator to generate plasma in the first magnetic sensor from a first start time to a first end time and generate plasma in the second magnetic sensor from a second start time after the first start time to a second end time after the first end time.
