On the primary side, the device according to the invention comprises: a primary coil (4), the surface (2) for mounting the secondary unit (3), a first temperature sensor (5) thermally coupled to the surface (2), a second temperature sensor (6) thermally coupled to the primary coil (4), and an evaluation unit (7) informationally connected to the temperature sensors (5, 6), wherein the evaluation unit (7) is configured to detect a foreign object (1) on the surface (2) in response to a rise in the temperature measured by the second temperature sensor (6) that is slower than a rise in the temperature measured by the first temperature sensor (5).",
