What is an electromagnet? What does electromagnetic mean? How do electromagnets work? Electromagnets use an electrical ...

Driving an electric current through a molecule can create a magnetic field. Yet in practice, such fields are often too weak ...

Plan a route, grab some snacks, and fuel up. Engineers and scientists have been sending massive magnets from U.S. Department of Energy (DOE) national labs on cross-country road trips. Magnets are at ...

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 ...

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 ...

Imagine trying to catch a fragment of a rocket nozzle in orbit above Earth’s atmosphere. The fragment is travelling faster than a bullet, and tumbling rapidly end over end. Around 27,000 orbiting ...

It’s easy to think about satellites as a bunch of mini-moons, orbiting the Earth seamlessly and without any (noticeable) movement. But that’s not quite right: satellites and other spacecraft often ...

Apple is considering ways it could use electromagnets to make changes to the way accessories or devices can magnetically connect to each other, including correcting alignment issues for covers and ...
