A levitation mechanism of high-Tc superconductors is created with the use of alternating-polarity magnets of the same size. It is verified experimentally that the levitation pressure can be optimized with respect to the width of the used magnets. The drag pressure depends greatly on the angle between the alternating-polarity and the moving direction. Coupling this levitation mechanism to repulsion forces due to pinning effect and Meissner effect as drive forces makes it possible to design a variety of actuators. This study describes the characteristics of the levitation mechanism, a developed prototype centimeter-size actuator, and the results of experiments for the test.
