Abstract
A heat generator () which comprises magnetocaloric elements () that are arranged in a circle about a central axis. A magnetic arrangement () of alternating magnetized and non-magnetized zones (), that is located within the circle formed by the magnetocaloric elements (), is rotatable around the central axis and co-operates with a field closing device () to loop magnetic flux generated by the magnetic arrangement () and alternately subject the magnetocaloric elements () to a magnetic field variation and create, alternately in each magnetocaloric element (), heating and cooling cycles, in synchronization with the circulation of heat transfer fluid which flows through the magnetocaloric elements () during the heating and cooling cycles. The field closing device () comprises a heat insulation ().
