The invention relates to a combined magnetic resonance imaging and targeting device for magnetic particles having a magnetic coil array. The magnetic coil array comprises a plurality of coils, each of which is connected to a power supply. The power supplies are connected to a controller which is embodied for two operating modes. In a first operating mode the power supplies are controlled in such a way that a magnetic field extreme value is generated at at least one location in a target region. In a second operating mode the power supplies are controlled in such a way that magnetic fields having a strictly monotonously rising or falling magnetic field profile are generated in an imaging region.
