The devices and methods of stimulating the immune system to treat damaged and abnormal tissue using compressed static magnetic fields provides for noninvasive treatment of damages tissue and removal of abnormal tissue. At least two magnets are positioned to have their static magnetic fields compressed at the damaged or abnormal tissue and at the immediately surrounding healthy tissue. The compressed static magnetic fields stimulate the immune system in the immediately surrounding healthy tissue which treats the damaged or abnormal tissue. The treated tissue fully regenerates without additional medical intervention. The devices provide for efficient exposure to compressed magnetic fields and ease of use at different locations on a body and different types of animal species.
