What is a magnetic fluid?

Magnetic fluid contains particles of magnetic materials mixed with liquid that act as a carrier. Under normal conditions, the material behaves like a viscous liquid. When exposed to a magnetic field, the particles inside align and respond to the field and show magnetized behavior. There are a number of uses for magnetic fluids, from medicine to industrial production, and are produced by various companies. Magnetic elements nanoparticles are used in the production of magnetic fluid to create a smooth and consistent fluid that will work well in different settings. The mixture usually includes a surface active substance that acts to prevent clogging in the presence of a magnetic field. The magnetic fluid must work well in different conditions and must be caution to prevent dirt that could prevent performance.

One use for magnetic fluid is medical in studies. Fluid can be injected as a contrasting agentLO for patients who receive studies of magnetic resonance imaging (MRI). As the fluid moves through the body, it will respond to the magnetic field and emphasizes the structures of interest and concerns about care providers. The patient's body naturally eliminates it over a few days or weeks, depending on which contrasting agent is used, and does not pose a disproportionate risk to the patient's well -being.

It is also possible to use magnetic fluids in shock absorbers, friction control devices, seals and many other applications. The ability to accurately create liquid can allow a number of characteristics to control. Companies may determine the necessary temperature and pressure range to develop a product that resists a potentially harsh environment. It can also hold, except for strong chemicals and other environmental contaminants while remaining functional.

magnetic colloidal fluid, as is also known, also has some less severe APLikace. Some artists work with it to create interactive pieces that can be displayed in settings, such as gallery and scientific museums. Members can play with magnetic fluid using magnets to change the polarization of the field around it. The fluid can also be left to its own devices in the contained environment that the artist programs to expose the magnetic properties to move the fluid and be colored or stained to create live visual images and dynamic, changing scenes.
