 note = {Im this paper, we study the nonlinear resonance phenomena and bifurcation phenomena in 1 degree of freedom magnetically levitated system. From the results of theoretical and experimental analysis, we clarify that the shape of resonance curve becomes soft type and period doubling bifurcations occur at the major resonance point due to the effect of the nonlinearity of magnetic force. We also show that the super harmonic resonance occurs with the shape of soft spring type.},
