Abstract

Levitation refers to free flotation, where the levitated object is suspended freely, against gravity without any physical contact. Among many levitation, magnetic levitation due to a finite-sized type-I superconductor was demonstrated and characterized. Here, we have developed a model by extending the two-loop method to calculate the levitation height for magnetic levitation within the superconducting microwave cavity and is compared with widely used mirror and finite-size superconductor method. The models were used to calculate the levitation height from the center and edge of the superconductor for magnet with strength 0.1 - 2.0 T. We observed a large discrepancy between the models for the edge levitation where our model underestimate the levitation height by 40-95%. Furthermore, in contrast to other models, our model has shown a superior capacity to calculate the levitation height at any location on the superconductor
