In this research, the principle of diamagnetic levitation is described briefly. The application perspectives of diamagnetic levitation and its advantages are as well discussed. By utilizing the magneto-Archimedes Effect to lift different seeds, the experimental procedures and parameters are provided which include magnetic characteristics of magnets and ratios of magneto-Archimedes solution. The theoretical derivation and finite elements simulation of force when the seeds suspend are conducted. These resolving formulas, methods of numerical simulation as well as means of experiments are meaningful as reference to the researches in this field.
