Invisible Forces

While we were discussing cool visuals using magnets, like this creepy ferroputty blob, I stumbled across this mind-bending high-speed video of iron particles suspended in an oily liquid, pulled to and fro in spikes and waves by invisible magnetic fields.

It’s our old friend ferrofluids again. Beautiful. Go full screen on this one.

fuckyeahfluiddynamics: Here a ferrofluid climbs a spiral steel structure sitting on an electromagnet. Magnetic field lines emanating from the sculpture’s edges tend to push the ferrofluid out into long spikes—part of the normal field instability—but surface tension resists. The short, somewhat squat spikes we see are the balance struck between these opposing forces. Though known for their wild appearance, ferrofluids appear many in common applications, including hard drives, speakers, and MRI contrast agents. Researchers have also recently suggested they might help understand the behavior of the multiverse. (Photo credit: P. Davis et al.) Ferrofluids will never stop fascinating me.

Things you should know about me: I can never get enough of ferrofluids. After you check out this art exhibit, here’s more examples of these amazing fluid-magnetic creations. holymoleculesbatman: Sachiko Kodama: The Art and Science of Ferrofluid Sachiko Kodama explores within her artwork ‘The Art and Science of Ferrofluid’ the pulsating nature of science and amorphous character of time and space based on the shape of magnetic waves… The Japanese female artist Sachiko Kodama was born in 1970. As a child she spent a lot of time in the southernmost part of Japan. This area is rich in tropical flowers and plants, edged by the sea, and washed with warm rain. Sachiko loved art and literature from an early age, but also had a strong interest in science. After Graduating Physics course in the Faculty of Science at Hokkaido University, in 1993, Sachiko matriculated in the Fine Arts Department at the University of Tsukuba, studying Plastic Art and Mixed Media. Then she completed Master’s and Doctoral Program in Art and Design at the University of Tsukuba. She studied Computer and Holography Art in her doctoral research. ‘Ferrofluids appear as black fluid and are made by dissolving nanoscale ferromagnetic particles in a solvent such as water or oil. They remain strongly magnetic even in a fluid condition which makes them more flexible than iron sand.’

razorshapes: The shapes seen in the image are about the size of a thumbnail. They are created by mixing ferrofluid with water color and putting it into a magnetic field. When put under a magnetic field iron particles in the ferrofluid solution start to rearrange, forming the black channels and separating the water colors from the ferrofluid. Some colorful ferrofluid goodness for your mid-week energy boost. Check out many more awesomely beautiful intersections of magnetism and art: My posts tagged “ferrofluids”

Ferienne

Your daily “wow” video.

Afiq Omar is back with another stunning crossover of physics and art. His previous work Ferroux used ferrofluids and other chemicals to create dynamic visual effects, haunting and exotic.

This latest video, Ferienne, uses more of those ferrofluids, taken to another level of visual complexity (and a pretty nice beat to boot). The shapes you see here are like peering into the invisible, using the ferrofluids to reveal the shapes of unseen magnetic fields. These are forms that we could never create in any other way, and are so random that each one may never be seen again.

Previously: At this rate ferrofluids are going to become my favorite thing on the internet. Don’t miss these dancing spires of “liquid wow” from a few weeks ago (plus more on the science of ferrofluids).

Aaaand now I’m obsessed with ferrofluids.

Join the club, Radiolab! 

Ferrofluids are a colloid, like mayonnaise, except instead of fat suspended in liquid there’s iron-containing particles that can respond to a magnetic field. The particles are so small that they can remain dispersed in the liquid instead of sedimenting, the way that sand sinks and river silt stays suspended. When a magnetic field and some kind of substructure is applied (here, the cones), you get something amazing.

The peaks and valleys that are created are due to the magnetic field preferring the liquid over the air (something called “normal-field instability”). You get liquid dancing in dimensions that you aren’t used to seeing, and you get the illusion of dancing, dynamic solids growing solely from a black lagoon.

I’m gonna need a minute. This was too cool.

Ferroux by Afiq Omar

Who says science and art can’t be friends? Afiq Omar mixes tiny portions of ferrofluid and other reactive chemicals to create stunning visual effects.

Silly Vimeo! No one says science and art can’t be friends!

This is a wonderful mashup of chemistry and art, and it reminds me of that one time that Robert Krulwich got all wonderful telling us about how ferrofluids demonstrate how bubbles pack together for comfort.
