A ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field. The name ferrofluid was . In this episode we will show you how to create your own ferro fluid using oil. Ferrofluid is a liquid that reacts to a magnetic field.

A ferrofluid (from the Latin ferrum, meaning iron) is a liquid which becomes strongly polarised in the presence of a magnetic field.

It is a colloidal mixture comprising extremely small magnetic particles suspended in a synthetic oil. This instructable will show you how to make your own ferrofluid. Comprised of nano-scale magnetic particles suspended in a transparent liqui undisturbed ferrofluid forms into a smooth pool. But when a magnet is brought close, ferrofluid reacts in strange and fascinating ways.

There are generally two ways you can make ferrofluid. How does $1a liter sound? Have you ever seen a liquid magnet?

If magnetic material is ground into an extremely fine powder, with a particle size of about nanometers (see Nanoguitar for more information on length units), and suspended in a liqui the resulting magnetic suspension is called a ferrofluid.

For audio speaker manufacturers, Ferrotec ferrofluid also provides significantly better speaker . With a comprehensive fluid development and applications laboratories in both the US and Japan, and an experienced staff of . Once within the magnetic field of a magnet, the previously runny liquid suddenly starts to grow spikes which grow higher as the magnet gets nearer and these spikes then repel each other, causing the patterns to move and change shape. Cooling is a crucial aspect of electronics design, all the way from high-power industrial applications to personal computers.

We investigate and develop ways of creating more efficient and reliable cooling systems, using magnetic nanofluids ( ferrofluids ). This not only takes advantage of the beneficial thermophysical . But suddenly, it leaps from a shallow pool to form a phalanx of rotating spikes. What on Earth is going on here? This is a ferrofluid : a liquid that becomes strongly magnetized in the presence of a magnetic field.

They claim that their technique, dubbed ferrohydrodynamic pumping, can be easily scaled up or down to be used in microfluidic devices or industrial-scale pumping devices, and . Ferromagnetic fluid forms spikes when the liquid is exposed to a magnetic field. When a magnetic field is applie the ferrofluid puffs out, creating some . He repeats the touching with a rubber glove on, and the ferrofluid leaves a permanent residue on the fingertip of the glove. Sci science factory Kevin Lin wants to do ever since he notices this interesting liquid.

However, it is not easily accessible to general public. Demonstrate magnetic fields in an incredible way! Creative unique sculptures with the help of magnets.
