There is provided a high speed solenoid having enhanced response characteristics. The high speed solenoid includes: a movable shaft linearly movable in an axial direction; a movable coil unit coupled to the movable shaft; and a magnetic field forming unit forming a magnetic field in a direction perpendicular with respect to that of a current flowing in the movable coil unit, wherein when a current is applied to the movable coil unit, the movable coil unit is moved by a magnetic field formed by the magnetic field forming unit to move the movable shaft. According to the high speed solenoid, the weight of a moving part is significantly reduced, and since an electrical time constant is small, a response speed of the solenoid may be enhanced. |
