1. A magnetic cooling apparatus comprising:

  • a plurality of magnetic regenerators comprising a plurality of magnetocaloric materials to emit heat when magnetized and to absorb heat when demagnetized, the magnetic regenerators being rotatably disposed on a circumference having a predetermined radius;

    at least one coil disposed on the circumference and coupled to the magnetic regenerators; and

    a plurality of permanent magnets provided inside and outside the circumference to generate a magnetic field to magnetize or demagnetize the magnetic regenerators, whereinthe at least one coil interacts with the magnetic field generated by the permanent magnets to rotate the magnetic regenerators.
