Abstract
A magnetic device is provided for a magneto caloric heat pump regenerator. Magnets are arranged within two magnetic flux circuits in a manner than that provides at least four fields of increased magnetic flux density. The regenerator can be used to move working units of magneto caloric material through the fields of increase magnetic flux to provide for heating and cooling as part of heat pump cycle. The orientation of the magnets provides concentrated fields of magnetic flux to induce the magneto caloric effect while optimizing the size of the magnets required to create the fields.
