We’re always happy to see hackers inspired to try something different by what they see on Hackaday. To [SimpleTronic] has a project that will let you stretch your analog electronics skills in a really ...

Researchers have shown that a pair of vertically arranged electromagnets can levitate and steer a magnetic robot inside a ...

Building an electromagnet vise (magnetic chuck) from transformer cores. The video shows disassembly, machining, resin potting ...

I like to analyze the physics of science fiction, and so I'm going to argue that the Merrie Melodies cartoon “Compressed Hare” takes place in the far future when animals rule the world. I mean, Bugs ...

It is a common grade school experiment to wind some wire around a screw, power it up, and watch it pick up paper clips or other ferrous materials. It is also grade school science to show that neither ...

One year ago, the 50-foot-wide Muon g-2 electromagnet arrived at the U.S. Department of Energy's Fermi National Accelerator Laboratory in Illinois after traveling 3,200 miles over land and sea from ...

Why did the 50-foot-wide electromagnet cross half the country? To help physicists discover new subatomic particles, of course. Mounted atop a 64-wheel trailer, a massive superconducting circular ...

Invented in 1824 by the British physicist William Sturgeon, electromagnets are a fixture of modern life, appearing in loudspeakers, motors, magnetic resonance imaging (MRI) machines, maglev trains, ...

Magnets like this one are great at picking up metal objects like these, but once you pick them up how do you let them go? For that you need a special type of magnet – an electromagnet. Magnetism and ...
