1. A method of making a magnetic regenerator for an active magnetic refrigerator, the method comprising:
- forming a magnetic regenerator from a slurry or a paste containing magnetocaloric material, the magnetic regenerator being formed to have paths in the form of plural discrete channels therethrough for the flow of a heat transfer fluid; and
varying the composition of the magnetocaloric material and/or the slurry or paste so that the magnetic transition temperature of the magnetic regenerator varies along the channels.
