An arrangement for magnetic particle imaging and a method for influencing and/or detecting magnetic particles in a region of action is disclosed, which arrangement comprises: magnetic particles in a region of action, the magnetic particles being influenceable and/or detectable, selection means for generating a magnetic selection field having a pattern in space of its magnetic field strength such that a first sub-zone having a low magnetic field strength and a second sub-zone having a higher magnetic field strengthare formed in the region of action, drive means for changing the position in space of the two sub-zones in the region of action by means of a magnetic drive field so that the magnetization of the magnetic particles changes locally, wherein each magneticparticle comprises a non-magnetic substrate with a layer of stainless steel.
