|Title||AC MAGNETIC FIELD MAGNETIC PROFILE MEASURING DEVICE AND MAGNETIC PROFILE MEASURING METHOD|
By scanning a space where an AC magnetic field is present, this AC magnetic field magnetic profile measuring device measures the magnetic profile of said space and the magnetic profile of an AC magnetic field generating device. This AC magnetic field magnetic profile measuring device is provided with a cantilever (11) at the end of which a probe is mounted, an exciter (12) which excites at the resonant frequency of the cantilever or a frequency close thereto, a vibration sensor (13) which detects vibration by means of the probe, a demodulation processing device (14) which demodulates the magnetic signal corresponding to the AC magnetic field at the position of the probe and separates the demodulated magnetic signal into the two orthogonal signal components differing in phase by 90 DEG , a scanning mechanism (15)
which scans the space where the demodulated magnetic signal is present with the probe, a data storage device which stores the two orthogonal signal components as initial data with unchanged initial phases, a modified data generator which reads in the initial data stored in the data storage device and generates data in which the phases of the initial data have been modified, and an image display device which displays a magnetic field distribution image.
