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).
Olympus e-510 Camera with stock 42mm lens. In this photo, 5400K Color balance 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.
As close as i could get with my kit lens and some cheap macro filters. A petri dish of magnetic fluid above a neodymium magnet. Lit with a variety of LEDs to paint in the reflections.

This is actually a fluid that forms this pattern when it experiences a magnetic field. The fluid has very tiny magnetic particles in it, which allow it to respond to the field. You can't see it in this picture, but there is actually a large magnet beneath the fluid.
Thanks to Matti Ryynänen for an excellent Nanotech demo!

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, the drop is just above the pool of fluid. It's slightly more elongated than I would expect, but it's hard to tell if that's from the magnetic field.
I also took some slow motion video to get a better idea of what's going on here.
