METALLIC FOREIGN COMPONENTS DETECTING APPARATUS AND METALLIC FOREIGN COMPONENTS DETECTING METHOD

摘要

In the metallic foreign matter detection apparatus for detecting metallic foreign matter contained in the object to be detected according to the embodiment, a sensor coil for detecting the metallic foreign matter by a change in a first electrical signal generated by applying a current to a conductor wound around a core is provided. A first sensing unit that detects the metallic foreign material magnetized by the magnetization unit using a first sensing unit and a second sensing unit that detects the metallic foreign material by using a change in a second electrical signal between the transmitting coil and the receiving coil due to the metallic foreign material. Can include.
