The lateral oscillations of a levitated body, which is moved in a horizontal plane and is guided by magnetic forces on both sides, are examined theoretically and experimentally. Considering the relative vertical motion between the body and the magnetic guides, a pair of nonlinear differential equations with periodic variable coefficients, which govern both lateral and yawing oscillations of a levitated body, is derived. By solving the equations, it is shown that there are three types of parametric resonances which are stable steady states of the resulting oscillations. Also, the physical meaning of the resonances are discussed theoretically. Furthermore, the above three types of parametric resonances have been observed with a simple experimental apparatus.
