PURPOSE: A magnetic device for protecting the internal surface of a water pipe is provided to enable the repair without stopping the boiler, and to economize on water resources and electric power through a water pipe. CONSTITUTION: A magnetic device(10) for protecting the internal surface of a water pipe includes a first, second, and third iron block(11,12,13), a pair of first and second magnets(14,15), a U-shaped protecting plate(16), and a pair of supporting pins(17,18). The first iron block has a T-shaped flat square body(111) and an arch-shaped plate(112) to the upper part of the body. The first and third block have each a square body(121),(131), an inclined flange(122),(132), and a through hole(123),(133). The magnets have each flat body and a N-pole and S-pole to the opposite side. The U-shaped protecting plate is made of stainless steel and has a pair of arranged through holes(161, 162) made by the fitting of the second and third iron block and the through holes(123,133). The arch-shaped contact surface is formed to the upper part of the magnetic device to be adhered to the outer circumference of the water pipe. Magnetic force is easily penetrated into the pipe.
