Abstract: A terminal may be provided with a magnetic regenerator unit using a magnetocaloric effect of magnetocaloric materials and a magnetic cooling system having the same. By a circular magnetic regenerator structure capable of evenly flowing heat transfer fluid and magnetic field and the flow of the heat transfer fluid being changed in the same way, and a magnetic band having a relative permeability, similar to a relative permeability of the magnetic regenerator, high efficiency of a flux generator may be obtained while reducing torque of a rotator. Power consumption for driving may be reduced due to the reduction of the cogging torque, and the magnetic band may be manufactured at a low cost by using inexpensive iron powder.
