1. An apparatus for creating pulse magnetic stimulation, in which pulse current is generated to create magnetic flux, the apparatus comprising:

  • a driving voltage supplying section for receiving AC voltage from a voltage source, converting the received AC voltage into DC voltage having a predetermined magnitude, and then outputting the DC voltage;

    a capacitor section for accumulating electric charge in accordance with the DC voltage;

    an input switch section provided between the driving voltage supplying section and the capacitor section, for controlling the accumulation of electric charge in the capacitor section;

    a coil connected in series to the capacitor section, for generating magnetic flux in accordance with current generated by both-end voltage corresponding to the electric charge accumulated in the capacitor section;

    an output switch section provided between the capacitor section and the coil, for controlling discharge of the electric charge accumulated in the capacitor section through the coil; and

    a shunt switch section connected in parallel between the coil and the output switch section, for lowering magnetic energy stored in the coil and voltage stored in the capacitor section into a ground level to obtain a pulse magnetic field.
