Scientists in Australia have developed an intriguing new technique for removing toxic “forever chemicals” from water. Adding a solution to contaminated water coats the pollutants and makes them magnetic, so they can easily be attracted and isolated.Con… Continue reading Magnetic solution removes toxic “forever chemicals” from water in seconds
[Glen Akins] had a WW2-era aircraft engine cowl flap indicator lying around (as you do) and thought it would make a jolly fine USB-attached indicator. The model in question is …read more Continue reading Interfacing An Old Engine Cowl Flaps Indicator To USB
Rare earth elements are a key part of electronic and mechanical devices, but they’re in short supply. Now, scientists have found a way to recreate a promising alternative – a “cosmic magnet” that normally takes millions of years to form in meteorites c… Continue reading “Cosmic magnet” recreated in lab as alternative to rare earths
The Earth’s magnetic field is something that many of us may take for granted, since it’s not something we can see, feel or hear. That last point has now changed though, as scientists and musicians have worked together to convert magnetic field data int… Continue reading Listen to the spooky soundscape of Earth’s magnetic field
Any project that contains something called a “flux modulator” instantly commands our attention. And while we’re pretty sure that [Retsetman] didn’t invent it after hitting his head on the toilet, …read more Continue reading Magnetic Gearbox Design Improvements Are Toothless but Still Cool
While there are now quite a few mini keyring flashlights on the market, most of them have to be held along with the keys when in use. YSMART London’s MQ3 is different, in that it magnetically – and quickly – pops on and off of a keyring-mounted base.Co… Continue reading MQ3 keyring flashlight features a quick-release magnetic base
Scientists in China have set a new world record for the strongest steady magnetic field ever generated on Earth. The hybrid magnet managed to produce a field measuring 45.22 Tesla (T), which is over a million times stronger than the planet’s own.Contin… Continue reading World’s strongest steady magnetic field generated in China

A new Sky Train test track in Southern China has debuted the world’s first maglev transit system built using permanent magnets instead of electromagnets. It’s capable of keeping its underslung carriages suspended indefinitely without a power supply.Con… Continue reading China’s “Sky Train” levitates power-free on permanent magnet tracks
Astronomers have measured the strongest magnetic field ever found in the universe. The honor goes to a powerful type of neutron star, with a surface magnetic field of over 1.6 billion Tesla.Continue ReadingCategory: Space, ScienceTags: Astronomy, Magne… Continue reading Astronomers measure strongest magnetic field ever detected
