A multi-layer magnetic device comprising two or more layers of containing magnets or ferromagnetic material to be applied to areas of the body of a mammal in which the first layer has one or more protrusions and the second layer has one or more receiving zones that are positioned to align with the protrusions of the first layer. At least a portion of the first layer has a first magnetic pattern, and at least a portion of the second layer has a second magnetic pattern such that, when the protrusions are aligned with the receiving zones, at least one region of the first magnetic pattern faces at least one region of the second magnetic pattern of like polarity thereby repulsing one another.一種多層磁性裝置，其包含將兩個或更多包含磁性或鐵磁性材料層施加到一哺乳動物之身體的區域，其中該第一層具有一個或更多的突出物，且該第二層則具有一個或更多的接受區域，其係佈置成與該第一層之突出物相對齊。該第一層之至少一部分具有一第一磁性圖案，且該第二層之至少一部分具有一第二磁性圖案，以致於當該等突出物與接受區域相對齊時，使得至少一區域之該第一磁性圖案面對相同極性的至少一區域之該第二磁性圖案，藉以使彼此互相排斥。
