摘要

Giving and/or method and the mechanism which detect those are disclosed influence in the magnetic particle in the action territory of the inspection object. As for the aforementioned method, in order for magnetization of the magnetic particle to change locally with the drive magnetic field which is formed by step and the drive expedient which form the selective magnetic field which possesses the spatial pattern of the kind of intensity of magnetic field where the 2nd sub zone where 1st it possesses low intensity of magnetic field with selective expedient, has the sub zone and a higher intensity of magnetic field is formed to the action territory, the aforementioned action which can produce effect with step and the reception expedient which change the spatial position of two sub zones in the action territory, with the change of spatial position of the 1st and 2nd sub zoneThe step which acquires the signal which depends on the magnetization of the territory and, it includes, selective expedient and/or drive expedient and/or reception expedient is formed as at least been movement possible part acquisition and/or during change of spatial position of two sub zones inside the action territory, vis-a-vis the inspection object.
