Abstract: The present invention relates to a magnetic actuation method according to which a magnetised mobile (4) is directed by means of at least one magnetic element (2, 2a, 2b) placed opposite said magnetised mobile, characterised in that the preferred direction (or easy axis) of magnetisation is made to turn at every point of said element by applying at least one mechanical constraint to said magnetic element(s) (2, 2, 2b), causing anisotropy within said element and thus moving the magnetised mobile in a preferred linear direction or causing the same to rotate.
