Abstract
This magnetic actuator comprises a fixed magnetic part (3) cooperating magnetically with a mobile magnetic part (1) and means (4) for initiating movement of the mobile magnetic part (1). The mobile magnetic part (1) comprises at least one magnet (1-1) and the fixed magnetic part (3) has at least two attraction zones (3-2) onto which the mobile magnetic part is able to come to attach itself. The mobile magnetic part (1) levitates when it is not attached to one of attraction zones (3-2), its movement being magnetically guided.
