Abstract: A system of two or more helmets used in team sports with magnetic material embedded in, or attached to, each helmet. Magnets are positioned identically in helmets so that the north magnetic field is facing outward. When two or more helmets come in close proximity, the like magnetic fields repel one another. This slows the velocities of the helmets, deflects the helmets as they collide, and generally causes helmets to move away from one another. This system is applicable for any sport or activity where concussive forces are caused by two or more helmets colliding, such as helmets in football, hockey, lacrosse, etc. When the helmet system is in place, magnets polarized in the same direction can be placed in other team equipment (e.g., knee pads) to mitigate blows to the head caused by that part of the body.
