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 new study suggests that humans can subconsciously sense Earth’s magnetic field. While this capability, called magnetoreception, is well known in birds and fish, there is now evidence that our brains are also sensitive to magnetic fields. The researchers from Caltech and the University of Tokyo measured the brainwaves of 26 participants who were exposed […]
Remember that school-room lesson on invisible forces where the teacher sprinkles iron filings over a sheet of paper that is placed over a magnet? Here’s a complete upgrade. Watch these magnetic field patterns in 3D, created when magnetite sand is thrown on magnets – some of them bouncing on a small trampoline – and shot […]
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.
