Abstract
A method of heating water comprises providing a helical passageway in juxtaposition a metal core rod and a coil through which an alternating current is passed. The alternating current generates an alternating longitudinal magnetic field that passes through the metal core rod and gives rise to eddy currents that generate heat. Water flowing along a helical passageway is heated and at the same time the water is magnetized as it cuts across lines of magnetic force of the alternating longitudinal magnetic field. A magnetized water generator for uses with the method comprises two bulkheads, a coil, a metal core rod and an outer tube. The core rod is disposed within the outer tube to create a helical passageway. The outer tube and core rod are disposed within the coil. A bulkhead is disposed on each end of the outer tube. Water enters the helical passageway through the water inlet in one end bulkhead and out of the helical passageway via a water outlet on the other end bulkhead.
