Abstract
An arrangement for influencing and/or detecting magnetic particles includes a selector 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 strength are formed in the region of action. A driver changes the position in space of the two sub-zones in the region of action by a magnetic drive field so that the magnetization of the magnetic particles changes locally, and a receiver acquires signals. The signals depend on the magnetization in the region of action, and the magnetization is influenced by the change in the position in space of the first and second sub-zone. The receiver has first and second compensators, each including a compensation coil.
