1. , a kind of layout (10) that is used for the magnetic-particle (100) of influence and/or detection effect zone (300), described layout comprises:

  • -selecting arrangement (210), it is used to generate the magnetic selection field (211) that its magnetic field intensity has space pattern, make second subdomain (302) that formation has first subdomain (301) of low magnetic field intensity and has higher magnetic field intensity in the described zone of action (300)-driving device (220), it drives the locus that (221) change described two subdomains (301,302) in the described zone of action (300) by means of magnetic, with this local intensity of magnetization that changes described magnetic-particle (100), wherein, described selecting arrangement (210) comprises that at least one contains the permanent magnet of high resistant permanent magnet material (213) (212).
