Abstract: A first plurality or group of magnets is mounted in a housing in a pattern having a circular cross section. A second plurality or group of magnets is mounted in spaced relationship with respect to the first group and means are provided for moving one of the groups of magnets relative to the other. A conductive member is located in the space between the two groups of magnets, in the magnetic field therebetween. Rotation of the one group and variation in the flux causes the conductive member to become heated. A fluid is then directed past the member, in heattransfer relationship with respect thereto, to cause the fluid to be heated and useable as a working fluid.
