A charging unit for wireless power transfer. The charging unit includes at least one coil for inductive power transfer, a sensor coil array with a sensing field for sensing the presence of at least one foreign object, and a controller. The controller is configured to move the sensor coil array and/or sensing field so that the sensing field can scan a sensing region, and configured to detect the presence of the at least one foreign object in the sensing region based on the sensing array output. The sensor coil array and/or sensing field is moveable such that the sensing field can be:a) positioned in the sensing region so that the sensing field does not overlap the at least one foreign object, and also b) positioned in the sensing region so that the sensing field does overlap the at least one foreign object.
