1. A heat generation apparatus using permanent magnets, the heat generation apparatus comprising:a plurality of rotors fixedly mounted on a rotating shaft, and configured such that they are rotatable along with the rotating shaft with permanent magnets disposed thereon at predetermined intervals;
a heat generation part configured such that the rotors are contained therein to thus form a predetermined gap between the heat generation part and the rotors, and adapted to generate heat while the permanent magnets are being rotated;
a motor configured to serve as a source for rotation of the rotating shaft; and
a power transmission means configured to transfer rotation force of the motor to the rotating shaft;
wherein insertion slits are formed in each of the rotors by a plurality of partitions formed through an outer circumferential surface of the rotor, and the permanent magnets are inserted into the insertion slits and arranged such that N pole of each permanent magnet is disposed at an identical end portion of each of the insertion slits in a radial direction and S pole of each permanent magnet is disposed at an opposite end portion of each of the insertion slits in the radial direction, thereby generating repulsive force between two neighboring permanent magnets; and
wherein the rotors are 2 to 16 in number and are mounted on the rotating shaft at predetermined intervals, and walls made of a material that does not pass a line of magnetic force therethrough are each disposed between two adjacent ones of the rotors so that the rotors are disposed in an independent state.
