Composite magnetic ring and energy converter

An energy converter having a construction comprising:

• a composite magnetic ring in which a plurality of permanent magnets are arranged in a ring shape at a prescribed spacing, and low-temperature Curie point magnetic substances having a Curie point at low temperature are sandwiched between each 2 adjacent permanent magnets, so that the plurality of permanent magnets and the plurality of low-temperature Curie point magnetic substances are situated in an alternating arrangement forming a ring,
• a rotor situated inside the composite magnetic ring and having a plurality of magnetic poles, and
• heating means that heats at least one low-temperature Curie point magnetic substance in the composite magnetic ring,
• wherein at least one low-temperature Curie point magnetic substance in the composite magnetic ring is heated to a temperature near the Curie point of the low-temperature Curie point magnetic substance by the heating means, and the magnetic permeability of the low-temperature Curie point magnetic substance is altered, thereby generating a magnetic field in the vicinity of the low-temperature Curie point magnetic substance, to cause rotation of the rotor.
