Abstract: There is provided a rotating apparatus with high efficiency by means of magnetic force, which comprises a stator ST in which a plurality of electromagnets 2 composed by winding a coil 1 around a core 10 formed of a strong magnetic material are uniformly arranged at the same intervals, the stator ST having a driving shaft hole 9 at the center in which a driving shaft 6 is freely rotatable and the stator ST being provided such that the driving shaft 6 is inserted in the driving shaft hole 9, and rotors RO in which the same numbers of permanent amagnets 3 as that of the electromagnets 2 of the stator ST are arranged at the same intervals as that of the electromagnets 2 of the stator ST on both right and left end surfaces of the stator ST, the rotors RO being fixed to the driving shaft 6 with a small gap 12 with the electromagnet surface of the stator ST.
