PURPOSE: A magnetic bearing and a rotator using the same are provided to remove the heat, noise, and abrasion caused by friction on a rotator, thereby extending the life span of the rotator. CONSTITUTION: A magnetic bearing comprises a ring-shaped inner magnetic member(50) and a ring-shaped outer magnetic member(60). The outer magnetic member is located outside the inner magnetic member at a certain interval. The inner periphery of the outer magnetic member is magnetized to the same first polarity as the outer periphery of the inner magnetic member. The outer periphery of the outer magnetic member is magnetized to a second polarity different from the first polarity. |
