Now this is a gadget. Just look at the 6-megawatt direct-drive generator, equipped with a huge permanent magnet rotor: it was designed by General Electric’s engineers and it is one of the largest of its kind that ever built.
I know most of the food we eat contains iron to some extent. And I also know that iron is vital to keep us going. But watching this awesome science experiment where corn flakes get attracted to a magnet creeps me out a little. This is why it happens:
Bike lights are massively important if you're cycling anywhere after sunset, but attaching them to your bike is a pain in the ass. These magneti lights could be the perfect solution—provided you ride a steel-framed bike.
Let's talk about magnet implants. I don't really bring it up much, but I have a small rare earth magnet implanted in the pinkie finger on my right hand. I've had it for around three years now.
The Pirate Bay, the largest torrent site on the Internet, is no more. Or well, it's not like it once was. As of this moment, they've taken down all torrent links on the website and will now only use 'magnet links'.
The reason people are so pumped about solid-state hard drives right now is because they're super-speedy. But if you think your SSD is fast, just wait until a new breed of laser-based hard drives comes to market.
Anyone who remembers high-school physics knows that a fluctuating magnetic field can induce an electrical current. That's the principle behind transcranial magnetic stimulation (TMS), where an electromagnet is held over the head and pulsed rapidly. Depending on the frequency of the pulses, this can either enhance or…
It's dangerous riding a bike in the city—crazy drivers swerving in and out can seriously hurt you. So the next time a crazy jerk cuts you off and almost kills you, throw this magnetic yellow card at his car.
Space-age jelly? A new art installation from Jeff Koons? A scary CGI sextoy massager? Let's all pull together now, before opinions are polarized even more...
If your microwave suddenly whizzes out your house and down the road, you'll know India's successfully built the world's largest magnet. The 50,000 tons of magnetised iron will be housed underground, making CERN's 37,500-ton magnet shrink in shame.
I don't know why you'd want to be a leftie, but at least we know the choice is out there if now. The magic causing the change of dexterity is called Transcranial Magnetic Stimulation, and is specifically intended for right-handers.
After 13 miners were trapped in a coal mine in Sago, West Virginia, four years ago, rescuers didn't know where to look for survivors — they could have been anywhere between 11,000 and 13,000 feet from the entrance. Radio waves can't penetrate very far through rock, so there was no way to communicate with the miners.
Sure, you could try affixing some magnets to the back of your iPad, and get the same iPad-as-fridge-magnet effect for far less, but then what'd happen if the iPad dropped and shattered? You wouldn't have anyone to sue but yourself.
Magnets have always been able to suspend soda cans in midair, haven't they? That's just basic science, right there.
Iron cobalt was the most magnetic material on Earth until physicists created what's in this man's hands. It's an iron and nitrogen compound which is 18 percent more magnetic and potentially disproves theories about how magnetic a material can be.
Between alcohol-fueled holidays and everyday health issues, some of us might eventually wind up needing new livers or some other organs. Turns out scientists could build us those new organs using metal nano-particles suspended in a magnetic field.
Ever trip over a power cord and launch your laptop across the room? Me either, but that's probably because of my laptop's MagSafe breakaway magnetic power adapter. If your laptop doesn't have one, check Lifehacker's guide for a DIY version.
Car designer Harsha Vardhan has a different vision of tomorrow. While his vehicle calls for an electric engine, just like we see in cars now like the Prius or Volt, that engine drives magnetic fields, not wheels.
