等を不要にできる効果がある。(Effects of the Invention) As described above, the superconducting pile driver of the present invention supplies current from the power supply device for the normal conducting magnet to the normal conducting magnet attached to the outer periphery of the guide member, and suppresses the magnetic field generated in the normal conducting magnet. The hammer is propelled upward by the Lorentz force generated as a result of interaction with the superconducting magnet installed in the hammer, and then the direction of the magnetic field generated in the normal conducting magnet is reversed, and the hammer is dropped by its own weight and downward driving force. Since the pile is struck and driven into the ground, the noise generated by the pile driver due to the explosion can be eliminated. In addition, since the driver is dropped by its own weight and the downward driving force, the impact force can be increased. In addition, since the current to the normally conductive magnet is simply controlled, the number of pile driving per unit time can be increased, and there is also the effect of eliminating the need for measures against oil leakage, etc.
