Magnets in Helmets Might Make Football Safer

A new football helmet design with a radical idea could possibly prevent concussions during helmet to helmet impacts by using magnets. The idea behind it is that each helmet would be equipped with a magnet. During a head to the head collision they would repel from each other and slow the impact force before contact. Tests are being conducted with rare-earth element neodymium magnets from China, which are the most powerful commercially available magnet. These can repel up to 100lbs of force when repelling from the opposite pole and weigh a third of a pound (compared to the 3.5 to 5 pound helmets). While these safety feature would add to existing ones it also would add $50 to $100 in price. If the magnets make it through field tests, they could theoretically reduce the relative risk of concussions by up to 80 percent without changing the appearance or intensity of the game.
