Title: Magnetic heating and cooling systems

A method is described for pumping heat for heating or refrigeration, comprising the steps of: exposing a system comprising a magnetic fluid to a magnetic field; causing the magnetic fluid to absorb heat of magnetization; transferring heat from the system to a heat sink; causing the magnetic fluid to exit the magnetic field, undergoing the cooling effect therefrom; and transferring heat to the system from a heat source.
