Claim:
1. A magnetic centring device for micromechanical applications, comprising: a magnet; a magnetic flux conduction device arranged on the magnet, the magnetic flux conduction device including a central magnetic flux conduction disc made of a magnetic material having a maximum relative magnetic permeability equal to or greater than 100, and a peripheral area arranged around the central disc and separated from the central disc by a non-zero distance; and a non-magnetic support made of a material having low magnetic permeability, the non-magnetic support being positioned above the magnet, wherein the central magnetic flux conduction disc and the peripheral area are positioned between an upper surface of the magnet and a lower surface of the non-magnetic support, the peripheral area being a magnetic flux conduction material arranged on the upper surface of the magnet or on the lower surface of the non-magnetic support.
