Three mechanisms, magnetically levitated by permanent magnets are
introduced and analyzed in respect of their balance and stability based on the nature of
attraction and repulsion by permanent magnets. The barycenter of the vehicle body is
above the magnetic suspension mechanism in one mechanism, below it in the another
two. The analysis shows that, among the three mechanisms presented in this paper, the
suspension mechanism combining magnetic attraction and repulsion can be statically
stable, while the other two can not.
