The invention relates to a device and a method for detecting error-free operation of a magnetic field monitoring busbar or a conductor ring for current measurement based on a magneto-sensitive sensing element. The aim of the invention is to detect an erroneous operation of a magneto-sensitive current sensor (1) comprising a busbar or conductor loop (2) formed in a measuring plane (11) of the current sensor (1), the current sensor (1) being capable of sensing the busbar or conductor loop (2) at least in a measuring region (12) on the basis of the magneto-sensitive effect, characterized in that the current sensor (1) is arranged in the measuring plane (11) of the current sensor (1). In the current sensor (1), a test conductor loop (3) is arranged in the spatial vicinity of a conductor loop (2) to be sensed, which test conductor loop (3) is arranged in a plane parallel to a measuring plane (11) of the sensing conductor loop (2) and is adapted to a predetermined main current path (21) of the conductor loop (2), in this way, a modulated test current (IT) of the test conductor loop (3) together with a current of the main current path (21) can be introduced into a measurement region (12) of the magnetosensitive induction current sensor (1).
