1. An imaging device comprising:
a. a magnet arrangement arranged radially around a sample volume and configured to generate a magnetic field B with a magnetic field component in a z-direction, wherein the magnetic field B changes during operation of the magnet arrangement,
b. a circuit board arrangement arranged radially within the magnet arrangement and having electrical conductor tracks divided into conductor track sections,
wherein the electrical conductor tracks are planar supply conductor tracks configured to supply only DC voltage,
wherein at least two of the conductor track sections adjoining one another form a structure section spanning an area,
wherein two respective ones of the structure sections form a structure section pair for each conductor track,
wherein the conductor tracks are arranged on the circuit board arrangement such that a change in the magnetic field B of the magnet arrangement induces equal and opposite voltages and/or currents in the two structure sections of each said respective structure section pair.
