A magnetic road is provided with a series of magnets having the same pole oriented upwards and an upstanding non-magnetic sidewall extending along at least one side. A magnetic object is provided having longitudinally spaced magnets which either have that same pole oriented downwards, or arranged in corresponding annuli having that same pole oriented radially outwards. In the first instance, additional provisions are made to prevent the object from rolling over. Accordingly, the object can translate along the road adjacent the sidewall while floating on mutually repelling magnetic forces.
