PROBLEM TO BE SOLVED: To provide a method and an apparatus for power generation by which large output power can be taken out against input by causing the running magnetic path having a high magnetic flux density held by a permanent magnet to exhibit high electromagnetically induc tion by opening and closing the magnetic path by generating alternating magnetic fluxes by means of magnetizing coils by inputting a small quantity of AC power to the coils. SOLUTION: The device for power generation (generator) is constituted by alternately arranging a suitable number of magnetization units and output units and connecting both ends of the arranged body to each other. In each magnetization unit, a permanent magnet magnetized to a required magnetic flux density is held in a closed magnetic path by means of a yoke composed of a soft magnetic body having high magnetic permeability and a magnetizing coil generating alternating magnetic fluxes which move forward or backward in the direction of the magnetic fluxes generated from the permanent magnet in the close magnetic path almost at an equal magnetic flux density to that of the magnet is provided on one side of the yoke. In each output unit, an induction yoke composed of the soft magnetic body having high magnetic permeability is provided in contact with the adjacent magnetization unit and an induction coil from which induced power is taken out is provided on one side of the yoke. By the method and apparatus for power generation, required AC power is inputted to the magnetizing coils and large output power is taken out from the inputted AC power.
