摘要： A magnetic field measuring device including: a vibrational probe unit having a probe that includes one or more material(s) whose intensity of magnetization is proportionate to an external magnetic field, a mechanical vibration source for the probe; a vibration detector detecting a vibration frequency and amplitude of the probe; an alternating-current magnetic field generator applying to the probe an alternating-current magnetic field; a direct-current external magnetic field generator applying a direct-current external magnetic field to the probe; a frequency modulation detector detecting frequency modulation occurring to the mechanical vibration of the probe; a direct-current external magnetic field controller adjusting the intensity of the direct-current external magnetic field applied to the probe; and a direct-current magnetic field determination unit determining a value of the direct-current magnetic field originating from a specimen.
