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.
