If you love a magnet, set it free. If it comes back to you, it’s due to a temperature called Curie. Look, I’m not a poet. Just read this.
More than a hundred years ago, physicists discovered that heat is simply the energy stored in the vibrations of atoms. This meant that heat and sound are related. Now, for the first time ever, scientists have experimentally shown that these atomic vibrations have magnetic properties, too.
C-29 was content to move packages along the assembly line until one day, when a shiny new model appeared on the opposite side of the conveyer belt. What happens next is extraordinarily sweet — and more than a little sad.
Let's start with a quiz…
Here's Veritasium's Derek Muller with 5 Fun Physics Phenomena to bend your brain.
In a technique similar to how optical fibre transports light through a tube, researchers from Spain have developed a material that efficiently guides and transports a magnetic field from one location to the other. The technology will likely be used to fuel the quantum computers of tomorrow.
Magnetic putty makes me deeply happy. It slowly deforms under a gentle pull, or snaps when abruptly tugged, while the magnetism will draw it like a creeping monster to devour stray magnets. While a handful of putty is fun, I am utterly enchanted by a monstrous 100-pound blob.
Remember those Newton's Cradle executive desk toys? They might be fun to play with, but you can't use them to send a piece of metal careening into someone's face. The Gaussian Gun uses the same principle — but it actually lets you shoot a projectile.
Marie Curie is one of the most famous names in science. Pierre Curie has somewhat been eclipsed by her fame. His name lives on, though, in one particular physical property, in honor of his research into magnets.
Here's a dazzling picture of the Aurora Borealis being simulated on a terrella. A terrella is not much more than a magnet that's been carved into a ball, but it has helped scientists both visualize and prove points about the Earth and its magnetic field.
This is what you see when you light a stick of incense, you just don't know it. A project sponsored by the Czech Ministry of Education makes smoke into flowers and creates trees out of magnets — and then photographs them all.
Ever seen The Blob? This is sort of like that – only the blob doing the absorbing is a ball of putty, infused with millions of micron-sized ferromagnetic particles. The putty is nothing special on its own, but watch what happens when you stick it next to a powerful neodymium iron boron magnet.
Holy crap this is excellent. Many of you are probably familiar with the intimidating crackle and flash of electricity-generating Tesla coils — but watch what happens when you combine them with wearable suits that behave like Faraday cages. It's like watching a shootout between Raiden and Emperor Palpatine.
Oil, watercolors and nanoscale iron particles make for some of the most psychedelic imagery this side of an LSD trip — and we've got the hi-res macro photographs to prove it.
One of the theories for the incredible navigational skills of birds is that they can sense magnetic fields through the magnetite in their beaks — essentially giving them a built-in compass. It's one of the more pervasive explanations, but it looks like it might not be true, at least for pigeons.
Some Frankenstein yeast cells had part of their own DNA removed and some human cell tissue put in. Why did this happen? So they could be so stuffed full of iron that they're super-magnetized and moved with magnets. Are us mere mortals far behind?
Being of the Hack 'em Off or Chew 'em Up school of nail design, I was unaware that there was such a thing as magnetic nail polish. Now that I've learned about it, let's take a look at the physics of a nail polish that forms fascinating patterns when exposed to a magnet!
Turtles are one of many species that use their sense of Earth's magnetic field to navigate great distances. But the magnetic field is constantly drifting, and that can cause major confusion in such a long-lived species. Here's their ingenious solution.
