Ferro fluid is a liquid mixture that is strongly attracted to magnets. This is due to its composition, which is made of magnetite particles suspended in a liquid base. This is a popular science class tool for teachers when helping students learn about magnets and their properties since it does not come in the normal solid form most magnets come in. One can do other interesting stuff with Ferro fluid that cannot be done with regular magnets.

Electronics
Ferro fluid is commonly used in electronics and in NASA. The substance is used as a protective coating for computer hard drives, while NASA is developing technologies that use the fluid in altitude control systems. In this technology, a magnetic field is used to influence the direction of the fluid. The substance is also used in magnetic resonance imaging in hospitals to detect structural and soft tissue abnormalities in the body.

Class Teaching Aids
This is perhaps the most popular use for Ferro fluid. The liquid is very easy to make for classroom use, since the teacher only needs to mix the magnetite particles with organic oil to produce the magnetic liquid. A popular mix for classroom use is composed of 5% magnetic solids, 10% surfactant to prevent the magnets from sticking or clumping together, and 85% carrier, which is usually kerosene. A commonly-used surfactant is oleic acid. Students can place the fluid on Petri dishes and watch the movement of the fluid as they move small pieces of magnets underneath the dish.

Interesting Liquid Sculptures
The interaction between Ferro fluid and magnets can create the most interesting shapes that can pass as art. For example, one can create numerous spikes of shiny black fluid when one places a magnet under a piece of glass with a small pool of Ferro fluid on it. One can create various sizes of spikes depending on the strength of the magnet. For example, the bigger neodymium magnets tend to produce the smallest spikes so one can use large and small magnets to create spikes of various sizes. Very weak magnetic fields produce varied sizes of lobes on the surface that are very interesting to look at. Placing three weak magnets in a row can produces three lobes on the glass plate that looks good enough to serve as a modern table centerpiece or the focal point in an office, very much like the moving Ferro fluid installations of Japanese artist Sachiko Kodama.

Ferro fluid is an interesting substance that is used for both practical and fun purposes. Aside from electronics and art, the substance is also a fun classroom tool that helps grade school children learn about magnets. In addition, with the flexibility of this substance, more practical applications for it are bound to be discovered in the future.

Ferro fluid is a magnetic liquid that is composed of magnetic particles, carrier fluids and a dispersing agent. When a magnetic field is applied to the substance, it becomes magnetized and takes on various shapes. Including oil-based, water-based and powder forms, there are different types of magnetized fluids and each one is specially formulated for a particular task. It is modified by using varying amounts of magnetic material and different liquid carriers. Because this unique solution has the characteristics of both a liquid and a solid, it is used for a variety of medical and commercial applications.

One of the principal markets for this material is loudspeaker technology. With more than 300 million speakers being produced with the solution each year, a whole series of various types of fluid is available for use in audio speakers. Headphones, tweeters, woofers and sub-woofers all require a different solution, and the solution is selected based on how much damping is needed. The fluid enhances the functionality of a speaker by improving its acoustical performance, reducing distortion and boosting its capacity to handle more power.

In research labs, hospitals and bio-medical settings, the water-based formula is commonly used for precision temperature control. A thermal version of the substance can be found in refrigeration systems, and it is also added to some scientific instruments such as microscopes and medical lasers. Using the solution to identify and treat cancer is still in an experimental stage. During this process, the liquid is injected into the body, and a magnet is used to move it to the cancerous area where it releases heat to destroy harmful cells.

The magnetic liquid can be found in a number of high tech gadgets, light fixtures and machines that require a reliable seal or lubricant. Referred to as a ferrofluidic seal, this seal is comprised of a magnetic fluid and a magnetic circuit that protects against moisture, vapor and debris while reducing friction. This kind of liquid seal can be found in a computer disk drive and rotating drive shafts on semiconductors, and it can last for several years before it begins to deteriorate.

A liquid-filled transformer that generates power is in development, but this equipment is unique because it will contain ferro fluid. The fluid is added to cool the transformer and reduce the effect of moisture. This technology also makes it possible to create smaller and more energy efficient transformers.

Due to its chemical composition and magnetism, ferro fluid is being used in many new ways. It is especially useful for solving a range of technical and engineering problems. In addition, because it can visually exhibit magnetic patterns, it is frequently used for everyday applications such as art displays and classroom experiments.
