Abstract: A magnetically inductive flowmeter includes a measuring tube having a tube axis and a tube wall; a magnet system for producing a magnetic field that extends perpendicularly to the tube axis; at least one pair of measuring electrodes for sensing an electrical voltage induced in the medium by the magnetic field; and an electronic measuring/operating circuit for operating the magnet system and the measuring electrodes. The magnet system includes a coil system having a coil having a coil core and further includes two pole shoes. The coil system includes a field guide-back, wherein a tangential fraction of the magnetic field in the coil relative to the measuring tube axis amounts to at least 90% of the total magnetic field. The field guide-back has a guide-back part that extends through the coil and forms the coil core of the coil.
