Abstract
The present invention is a helmet system that reduces concussions by damping rotational force transmitted to a helmet user. The helmet has an helmet shell that moves independently from an internal body worn by the user. At least one magnetic force emitter on the helmet shell's interior directs at least one interior-facing magnetic flux axially at the internal body. At least one magnetic force emitter attached to the internal body directs at least one exterior-facing magnetic flux at the at least one interior-facing magnetic flux. In a resting state magnetic flux interactions are limited.…
