Zusammenfassung:	A measuring apparatus for measuring losses in a circumferential segment for an electrical machine is provided. The measuring apparatus includes a frame to which a circumferential segment is fixable and a flux element attached to the frame so that a circumferential segment fixed to the frame and the flux element are radially distanced and that a magnetic flux generated by a current flowing along the coil windings housed in one slot of the circumferential segment follows a magnetic flux path including at least a first path portion in one tooth circumferentially adjacent to the one slot, a second path portion in the yoke, a third path portion in the other tooth circumferentially adjacent to the one slot and a fourth path portion in the flux element.
