<p>Magnetic turntable Abstract The invention relates to a magnetocaloric device, especially to a magnetic turntable. The magnetic turntable includes magnet groups consisted of a plurality of pieces of permanent magnets arranged with alternating polarities, the magnet groups are housed in first 5 through holes, there is provided a nonmagnetic cover on the top of the mounting disc having a magnetic bottom board, the bottom board, mounting disc and the cover are tightly connected together by fixed blocks, the transmission shaft penetrats the blind hole and radially has a transmission arm, there is provided a first slot 10 cooperating with the transmission arm and a second slot cooperating with the wall to the transmission block emboling the transmission shaft; conductor cuts more magnetic lines in the strong magnetic field caused by turning the magnetic turntable in the case of no AC power, therefore, the magnetic turntable can obtain higher efficiency 15 of magnetocaloric effcet.
