反重力跑鞋让你体验月球漫步

“月球漫步者”跑鞋的外观与普通跑鞋并无不同，它的独特之处在于藏在记忆海绵下的两层特殊材料，嵌入了世界最强力的磁铁。据该公司介绍，“每层材料里都有强力N45磁铁，嵌入的位置正好使上下两层磁铁的N极相对，产生的互斥力使人们脚步变轻，可以像宇航员一样轻松愉快地行走。”

Speaking to Live Science, mechanical engineer Patrick Jreijiri, the brains behind MoonWalker, explained that the strength of a magnet depends on its composition – a mix of neodymium, iron, and boron. So he chose N45, which is not only the strongest but also cheaper than most magnets. The pieces he chose for the shoe range from 2.5 to 5 cm in diameter, and are capable of moving 12 to 24 kilograms of material each.

“月球漫步者”运动鞋的创意来自机械工程师帕特里克·杰吉里。在接受生命科学网采访时，他解释说磁铁的磁力由磁铁的构成决定，包括钕、铁和硼，因此他选择使用N45磁铁，既有最强磁力，也比多数磁铁便宜。他选择使用的磁铁片直径在2.5~5厘米之间，每片磁铁都能承受12~24公斤的重量。

The two special layers, embedded with 12 to 13 magnets each are arranged in such a way that the north poles of the magnets face each other. These poles repel each other, creating a gap, or force field, between the layers. So when the wearer’s foot pushes against the combined strength of the magnets, the gap will act as a cushion, keeping the wearer suspended in space. Of course, there’s a limit to how much weight the magnets can withstand and in the case of MoonWalkers that limit is 183 kilograms.
