Abstract: Dual frequency AC magnetic field effects are analyzed in the case of levitated samples heated, melted and confined. The time dependent numerical models based on accurate spectral approximation give an insight to oscillation patterns and stability conditions for a copper sample both in solid and liquid state after the melting stage. Application to microgravity experiments planned at International Space Station and the full gravity magnetic levitation for the similar sample are presented.
