Summary:The present invention relates to an inductor in which an inductance can be changed comprising: a core; a first coil wound on the core in which a current flows; a second coil wound on the core in which the current flows; and a control part that changes an inductance by controlling a size and direction of the current flowing in the second coil, wherein having a characteristic of changing the inductance of the inductor according to the size and direction of the current flowing in the second coil. 본 발명은 인덕턴스를 변경할 수 있는 인덕터에 관한 것으로 코어, 상기 코어에 권선되어 전류가 흐르는 제1코일, 상기 코어에 권선되어 전류가 흐르는 제2코일 및 상기 제2코일에 흐르는 전류의 크기 및 방향을 제어해 인덕턴스를 가변시키는 제어부를 포함해, 제2코일에 흐르는 전류의 크기 및 방향에 따라 인덕터의 인덕턴스를 가변하는 특징을 갖는다.
