A magnetic energy wave device, including a coiled spiral tube, a magnetic metal layer, hollow blocks and the circuit board coil. The spiral tube where the coil of the magnetic is interlinked with the switch unit; the magnetic metal layer sets in the peripheral direction of the coiled Spiral tube; the helical coiled tube and the magnetic metal layer is located at the seat of the hollow coil within the hollow outer coil winding coil seat; the external power supply circuit board electrically connects to the switch and the magnetic quality coil; this way, when the water flows through the inlet, the magnetic switch initiates the power and coil. The coil and the magnetic metal layer generate a dynamic magnetic field in order to fully magnetized water in the tube.
