Comparative study between three models for the levitation height calculation

Magnetic levitation has been demonstrated and characterized within the coaxial microwave cavity [1,2]. A permanent neodymium magnet is levitated from the edge of the finite-size superconductor [3,4]. One challenge is to develop a better method to calculate levitation height [5]. This paper compares three models, the Mirror method, finite-size superconductor, and two-loop model, for the levitation height calculation. The limitations and advantages of each model are discussed in detail.
