The culmination of cutting-edge technology! A liquid material that responds to magnets and is utilized in various industrial applications.
"Magnetic fluid" is a liquid material developed in the early 1960s as part of NASA's space program, addressing the question of how to transport liquid fuel inside a spacecraft in a state of weightlessness in outer space. It consists of three main components: magnetic microparticles, surfactants, and a base liquid that provides fluid functionality. Because it uses extremely small magnetic particles, sedimentation or separation due to gravity does not occur, and the surfactant that coats the microparticles prevents aggregation even under strong magnetic fields. [Magnetic Properties (Superparamagnetism)] - When the magnetic field is zero, it is simply a non-magnetic liquid. - Magnetization occurs when a magnetic field, such as that from a magnet, is applied. - When the magnet is removed (the magnetic field is taken away), the magnetization disappears again. - It does not possess characteristics such as remanent magnetization or hysteresis.
