Abstract
A linear solenoid has a moving core, a main coil, and a magnetically attractive core. The moving core is supported to be capable of sliding in an axial direction of the moving core. The main coil winds around the moving core and forms a tubular shape. The magnetically attractive core magnetically attracts the moving core based on magnetic force caused by the main coil. The linear solenoid may further have a secondary coil disposed separately from the main coil so that the secondary coil intersects with the moving core at a position corresponding to the secondary coil when the moving core moves toward the magnetically attractive core.
