Magnets are a fairly common type of material with special magnetic and electrical properties - and regardless of the shape of the magnet, they are all one way or another made of solid material. However, a team of chemical engineering specialists from the University of California was able to create an unusual liquid magnet based on unique 3D printing technology and an equally unique approach to creating liquid nanoparticles based on ferrofluids. As a result, scientists turned out to be a real liquid magnet with similar properties of magnets.
More precisely, the properties of the new liquid magnet are such that they can be easily changed by applying any traditional magnet made of solid material to the new type of magnet - thus changing the properties of one magnetic field using another. As for the development itself, the scientists first conducted an experiment with ferro-fluids - a special type of fluid-solutions containing iron oxide particles, and managed to create an improved solution in which iron nanoparticles were placed.
After completing the additional stabilization step, they also conducted additional studies and found out that to create liquid magnetic droplets they need to ensure strong bonding of the nanoparticles to each other even at the smallest possible size indicator. This resulted in the development of a conceptually new 3D printing technology, which offered the possibility of organizing liquid magnetic droplets of less than 1 nm in size, which is really an impressive indicator, given that the ferro-liquid solution has an unstable character in one way or another.
As a result, scientists have proposed a conceptually new approach to the creation of a liquid magnet, which can change the degree of its magnetic properties and shape depending on what needs to be done in a given time interval. In addition, the new magnetic design clearly demonstrates that printing has some additional features that can be further improved and brought into line with additional materials.
