A magnetic heat pump system which arranges permanent magnets at the two sides of a magnetocalorific effect material to thereby strengthen the magnetic field to improve the cooling and heating ability, which magnetic heat pump system uses first and second magnets which move inside and outside of the containers in the state facing each other to change a magnitude of a magnetic field which is applied to a plurality of containers in which a magnetocalorific effect material is stored so as to change a temperature of a heat transport medium which is made to flow through the containers by a reciprocating pump, the intensity of the magnetic field which is applied to the magnetocalorific effect material in the containers being increased to enlarge the change of temperature of the heat transport medium which is discharged from the magnetic heat pump and improve the cooling and heating efficiency.
