A revolving core inductor is provided to simplify and stabilize the structure of a body by rotating a core instead of a coil or a permanent magnet. A revolving core inductor includes a body(100), an induction operation coil(110), a revolving core(150), and an extended core(151). The induction operation coil(110) is installed in the body(100), and protects a coil in a central through unit. The revolving core(150) penetrates through the central through unit to revolve, has the extended core of a predetermined direction, and an induction coil, a magnet or a permanent magnet for operation in the range of a magnetic pole of the extended core.
