As a kid, I grew up near minutes from the beach and many times saw grownups meticulously sifting through the sand with a metal detector. I imagined they were pulling up diamond rings and pirate's gold. My dad assured me they weren't, though I suspect he just didn't want to buy me a metal detector.
In any case, these magnet fishing hobbyists have them beat.
By dropping a very strong magnet underwater, history buffs "WW2 Wendal" fish their local lochs and rivers for valuable metal objects. They primarily explore WW2 sites for discarded war artifacts but often reel in non-military items such as stolen safes and, well, junk. Sometimes they find nothing at all but, judging from their videos, that doesn't break their spirit.
A team at MIT’s Department of Mechanical Engineering and Department of Civil and Environmental Engineering have created a set of foldable, 3D printed robots that are doped with magnetic particles that are precisely aligned during printing; when triggered by a control-magnet they engage in precise movements: grabbing, jumping, rolling, squeezing, etc.
MIT researchers designed and 3D-printed an array of soft, mechanical critters that are controlled by waving a magnet over them. The shapeshifters that fold up, crawl, grab things, and snap together into intricate formations may someday lead to new kinds of biomedical devices. For example, one of the devices “can even be directed to wrap […]
