Intorudction of magnetic fluid/ferrofluid                                                                            

 

Magnetic fluid is an unusual fluid in that it is attracted to a magnet. In the 1960s, NASA developed the magnetic fluid as part of its space programs. Magnetic fluid has three ingredients: ferromagnetic particles such as magnetite and composite ferrite, surfactant, and a base liquid such as water or oil.
The surfactant coats the 10 nm-dia ferromagnetic particles to avoid coagulation and keep them stably dispersed in the base liquid, forming a ferromagnetic fluid. Its dispersibility also remains stable in high magnetic fields.

This photo shows a phenomenon called 'spiking' that occurs when magnetic fluid is placed in a container and a magnet is brought under the container. Magnetic force acting on the surface of the magnetic fluid produces 'spikes', that look like large nails sticking out of the surface.
