PURPOSE:To obtain the magnetic device which is capable of not only a linear movement generating, simple, forcible, high accelerating and easily direction control but also magnetic force storing and electric power generating by generating electro-magnetic force in a coil through crossing of lines of magnetic force and induced electric current at the one of the lines of magnetic force and moving any of a solenoid coil or ram integrated to a coil. CONSTITUTION:A solenoid coil 1 is provided concentrically on the external circumference of a tube 2, a ram 6 is provided while a gap 7 of magnetic path is formed at the inside, a coil 4 is provided at the external circumferenc of the ram, the ram and the coil are integrated, the coil 4 forms a closed electric circuit, a magnetic return loop circuit 5 is formed at the other end of ram, a magnetic flux 2 in the side of solenoid coil and magnetic earth are formed, current is applied on the solenoid coil 1 in the direction from dot to plus or the inverted direction, the ram is moved by generating a magnetomotive force F in the direction the other end, a current is turned OFF, a spring which, although not illustrated, pushes or pulls the ram in combination with the solenoid coil is provided at the one and the other ends, thereby the ram is returned to the initial position. |
