Scientists can develop the first magnetic fluid in the world

Researchers have discovered the first magnetic fluid that can remain magnetically, even when it changes its shape, predicting the development of liquid robots. Thickness consists of nanoparticles floating in a solution that usually acts as a magnet when in a magnetic field.

The team managed to use a special blend of polymeric oils to push particles that are very close to each other on the surface of the liquid so they can keep maggots.

Thomas Russell, a college scientist from Massachusetts, and his colleagues spent seven years in developing a simple way to convert so-called "magnetic magnetized liquids" – ordinary metal particles that float into liquid – into a permanent magnet.

Scientists call most of the permanent steel magnet you can find on the fridge at home, the "Iron Magnet". Once exposed to a magnetic field, the axis of rotation of its electrons is biased and stays as it heats to a high degree.

Magnetic iron materials can be divided into nanoparticles and "suspended" in liquid, creating "magnetic fluids" that remain magnetic when placed in an external magnetic field. Once this area is removed, the individual particles become free to move and all magnetism is lost.

Professor Russell and his team found that the droplets of droplets could remain magnetized if the particles were applied to the surface of each drop – just eight nanometers between them. This forms a layer around the outer fluid, acting as a solid magnet, retaining total magnetism and moving it to the liquid center.

Thus, when the droplets are exposed to an external magnetic field, each of the billions of nanoparticles on the surface of the drop interact and 70 billion of those drooping in the drop in perfect harmony.

In addition, researchers found that these droplets can retain their magnetic properties when divided into smaller droplets. The exquisite quality of stools is the possibility of changing the shape to adapt to the environment, turning into new forms, without losing its magnetic properties.

Researchers expect to find practical applications of various new renewable magnetic fluids, such as the design of magnetic-powered liquid robots, and publish the full research results in the journal Science.
