Abstract: Generator (1) of electrical energy made up of two permanent magnets (3) arranged one after another at a set distance; a magnetic field separator disk (5), which acts between both magnets; a rolled-up coil (7) on the prolongation of the nucleus of one of the permanent magnets (3) and an impulse mechanism for the rotating disk that can be a wind turbine (10), a very low-powered electrical motor, or any other external means. The field separator is made up of an iron disk, that is, of ferromagnetic material. Near its periphery, a series of four or more windows (5.1) has been made, allowing the poles of the permanent magnets to interact directly. The distance between each permanent magnet and the separator disk is about two millimetres.
