We demonstrate a method to produce phantoms with arbitrary and easily adjustable susceptibility distributions. Objects in a magnet bore cause high order inhomogeneities not correctable by shimming, and confound magnetic field mapping and phase unwrapping algorithms. We show a wire winding carrying direct current can simulate an object of adjustable susceptibility, for rapid testing of field mapping and phase unwrapping methods.
