To provide a system for preventing the clogging of a well by applying a magnetic field to flowing water to bring a scale-causing substance to a state being unable to precipitate.
The system for preventing the clogging of the well by applying magnetic treatment to flowing water includes a screen having fine water passing holes provided to the lower part to be embedded in the ground of its peripheral wall by drilling over the whole periphery thereof, a coil-shaped conductive part spirally extending along the surface of the screen in the longitudinal direction of the well to be integrated with the screen, and a power feed part for feeding power to the coil shaped conductive part, and is constituted so that the pitch of the coil shaped conductive part in the longitudinal direction of the well is made larger than the width of the coil shaped conductive part in the longitudinal direction of the well so as to form gaps between the adjacent coil parts of the coil shaped conductive part to allow them to communicate with the inside of the screen through the water passing holes, the surface of the coil-shaped conductive part is insulated and an electromagnetic field is formed inside or outside the well by passing an electric current through the coil-shaped conductive part to prevent the adhesion of a clogging causing substance in water to the screen.
