A method for heating a fluid in a pipe by transforming induced current flowing through a conductor directly to heat energy as the conductor moves through a magnetic field. The method comprises locating N and S poles of a magnet adjacent the outer peripheral surface of a pipe on opposite sides, respectively thereof. A conductor in the form of heating wires is secured to a central shaft in the interior of the pipe. The heating wires have portions orthogonally intersecting with a magnetic line of force defined between the N and S poles and constitute a closed circuit. An impeller secured to the central shaft is caused to be rotated by the flow of the fluid flowing through the pipe, which in turn causes simultaneous rotation of the heating lines fixed to the central shaft. As a result the heating lines are heated due to induced current generated therein. This, in turn, heats the fluid.
