A magnetic-inductive flowmeter with a measuring tube having a measuring section, a magnetic field generating apparatus for generating a magnetic field in the measuring section of the measuring tube, and two electrodes which are located in the measuring section of the measuring tube for detecting the measurement voltage, the magnetic field generating apparatus having magnet coils which are located outside of the measuring section of the measuring tube and have a respective coil core. The cores of the magnet coils with reference to the magnetic flux make contact with two yoke elements via magnetic connection elements in a magnetically highly conductive manner and the yoke elements partially border the measuring section of the measuring tube.
