This Golf Ball-Sized Magnet Creates Three Tonnes Of Force

This little superconducting magnet may look serene, but it’s actually a record breaker, capable of creating three tonnes of force. The magnet beats a record that has stood for over 10 years, generating a magnetic field of 17.6 Tesla — that’s more than a typical MRI machine, or about 3000 times more than a refrigerator magnet — beating the previous best by 0.4 Tesla.


Hit This Magnetic Bullseye And You'll Never Misplace Your Keys Again

Are you prone to losing your keys more often than you’d like to admit? You just need to settle on a specific place to put them every time you get home. And to make this routine enjoyable enough so that it becomes a habit, trying to hit this magnetic bullseye when you get home every night sounds entertaining enough.


Watch A Floating Pillow Somehow Support The Weight Of A Brick

How is this floating pillow supporting the weight of this brick? Magic? Some sort of invisible string? Maybe it’s an illusion to make it look like the pillow is floating and spinning but it really isn’t? CGI!? Nope.


Magnetic Cello Comes With No Strings Attached

Last year’s laser violin was the first re-imagined stringed instrument that didn’t actually have any strings. And not to be outdone in the orchestra pit of the future, this year it’s the cello’s turn to get a fancy stringless upgrade. But instead of lasers, the Magnetovore opts for magnets, requiring the musician to play it like a sort of cello/theremin hybrid.


Reading Glasses With A Built-In Secret Neck Strap

If you require reading glasses, you’ll inevitably get to an age where you tire of constantly misplacing them and just accept that a neck strap is the way to go. But they’re actually a handy accessory, and if you want to make the upgrade earlier without looking 20 years beyond your age, this pair of reading glasses actually features a secret integrated neck strap.


Feel Flux Review: A Scientific Toy That Feels Like Magic

Juggling is hard. Keeping those balls aloft against the relentless forces of gravity takes skill. But what if you could just make gravity work a little bit differently? With the Feel Flux, you can.


These Glasses Swap Screws For Magnets In Their Hinges

Good news, klutz: these glasses swap the usual screws in their hinges for magnets, allowing you to swap the arms easily — and making them harder to break too.


Tiny Magnetic Robots Might One Day Work On Equally Tiny Assembly Lines

We’ve successfully engineered giant robot arms for building cars on an assembly line. But smaller mass-produced items — like electronics — still mostly rely on the nimble hands and fingers of a human. Building and controlling robots on a very small scale is still very difficult, but a company called SRI International may have found a clever solution using magnets.


Magnetic Building Blocks That Interact With Touchscreen Tablet Apps

There’s a fear that touchscreen devices like smartphones and tablets will one day turn kids into lifeless, imagination-less zombies. But technology isn’t all bad. And to bridge the gap between the toys of yesteryear and tomorrow, researchers at the National Taiwan University created a building block toy that can interact with apps on a touchscreen tablet.


GE Has Found A Way To Cool A Fridge With Magnets

At one time giant blocks of ice were the best solution we could come up with for keeping food cold. That primitive approach was eventually replaced by electric refrigerators using compressors and chemical coolants. Now, almost 100 years later, GE thinks it’s found a better way to cool a fridge using a water-based fluid and magnets.
