This application provides a wireless charging foreign object detection apparatus, applied to the field of wireless charging technologies. The detection apparatus includes: an excitation coil configured to provide a time-varying magnetic field, detection coils configured to detect a foreign object, and a processor configured to determine whether a foreign object exists. The detection coils may include two detection coils, or may include at least three detection coils. The at least three detection coils may be further configured to eliminate a detection blind spot.
