Claim 0:
1. A supporting device to slidingly support, and linearly move along an axis an object, comprising:
an empty channel extending parallel to the axis,
a magnetic flux generator for creating a magnetic flux that crosses a segment of the empty channel with magnetic field lines which are all equally-oriented,
a first element, reactive to the magnetic field, which is arranged in the empty channel and which extends along said axis,
the first element being configured to slide relative to the channel parallel to the axis during the movement of the object,
wherein the first element in correspondence of said channel segment has a cross-section which, seen in a plane orthogonal to the axis, has a dimension along the width of the channel,
the first element having a length considered along said axis,
wherein said dimension has a value that varies along the length of the first element parallel to said axis so that where said dimension reduces or increases there develops a force tending to move the first element relatively along the axis with respect to the channel in order to bring the first element and the channel back in a certain relative position.
