ferrofluid close-up. A ferrofluid (portmanteau of ferromagnetic, and fluid) is a liquid which becomes strongly magnetized in the presence of a magnetic field. Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water).

A liquid that reacts to the presence of magnetic field, taken on a recent trip to london to visit friends.

Could you magnetize pipes enough to keep all the sand, silt and general goo in the middle of the pipe and reduce corrosion... Large Hadron Collider style :) obviously using less power though :)

Conference held in the Science Museum today - fascinating day kicked off with a fast talk about the history of electricity. After the formal sessions, we were let loose in the WonderLab – where I played a theremin, made a ferrofluid look like a hedgehog, built a cantilevered structure and watched ice crystals form.

The ferrofluid was fascinating - basically a magnetic liquid, orginally invented by NASA to move rocket fuel.

Ferrofluid doing its thing

A drop of ferrofluid with a magnet under it.

I wanted to see if the force of a magnetic field on ferrofluid (a ferromagnetic liquid) would overcome the surface tension of a droplet.

In this photo, small droplets are rebounding from the splash. Notice the unusual string-like structure. I don't know if it's caused by the magnetic field, but seems very unusual.

I also took some slow motion video to get a better idea of what's going on here.

Fun with some ferrofluid. This can be homemade or bought on-line. Also know as liquid magnets, this stuff looks like used motor oil until you place a magnet underneath it and it forms little spikes along the magnetic fields. It's wild to see it in motion, check YouTube keyword ferrofluid.

"Metallic Liquid Lollipop"

What you see before you is a small, cylindrical magnet.......engulfed in printer toner. To be more accurate, this is ferrofluid, violently adhering to a magnet. The liquid is innocent enough, though it stains everything it sees. It contains ferrimagnetic particles, suspended in a carrier fluid. If you ever watched "Terminator 2", this stuff basically behaves like the T-1000. In the company of a magnet.....this stuff is freaky!! So, I dipped this little magnet into the fluid, and it formed this ball....and the spikes. The spikes are a result of the particles orienting along magnetic field lines. Did I mention that this stuff is crazy? While attempting to put this ball of goop back into the bottle from which it came, the ball basically bounced on the bottom of the bottle, while still adhering to the magnet. Anywho, there are two large strip boxes (they should be evident), and a snooted speedlight above, just to highlight the spikes. Lastly, there is a bare speedlight lighting the background. When I only lit the background, I was looking at a black hole. Remember, without something to reflect, black is bllllllllaaaaaaaack!!! I look forward to future experiments with this stuff. Thanks for popping by!!

Ferrofluid, with a neodymium magnet buried inside. Yeah, oops. Don't do that. It turns out to be quite difficult to remove magnetic liquids from magnets.

Olympus e-520 Camera with stock 42mm lens. In this photo, auto-shoot mode was used. Material that was used was Ferrofluid. Essentially ferrofluid contains iron particles suspended in an oil carrier. Since it contains iron, the fluid can be subjected with a magnet (magnet was placed underneath the fluid) and each spike that is shown are the lines of the magnetic field.

quite blurry on my camera but still neat.
