| 发明名称 | Magnetic actuation method | ||
| 摘要 | The present invention relates to a magnetic actuation method according to which a magnetized mobile (4) is directed by means of at least one magnetic element (2, 2a, 2b) placed opposite said magnetized mobile, characterized in that the preferred direction (or easy axis) of magnetization 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 magnetized mobile in a preferred linear direction or causing the same to rotate. | ||

| 主权项 | 1. A magnetic actuation method, according to which a magnetized mobile (4) is steered by means of at least one magnetic element (2, 2a, 2b) set facing said magnetized mobile, wherein the preferred direction (or easy axis) of magnetization is spun throughout said element round by the application of at least one mechanical stress to said magnetic element(s) (2, 2a, 2b), causing an anisotropy within said element and thus driving the magnetized mobile in a preferred rotation or linear direction, wherein the mechanical stress applied is a unidirectional stress resulting from the bidirectional combination of two unidirectional stress preferably applied along two intersecting directions substantially 45° apart. | ||
