A multi-layer magnetic device comprising two or more layers 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.
