Dancing magnetic fluid

Dancing Magnetic Fluid - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Scientific Principle Introduction:

Operating instructions: Place the handle close to the magnetic fluid and observe the changes in the magnetic fluid. Function Overview: This exhibition items consist of magnetic fluid, permanent magnets, manual operating devices, etc., showcasing the characteristics of magnetic materials in a magnetic field. The audience manually controls the permanent magnet to approach or move away from the magnetic fluid, observing the changes in the magnetic flowers formed by the magnetic fluid. Scientific principle: In the 1960s, American scientists were the first to successfully solve the problem of rotating seals using ferromagnetic materials. In experiments to eliminate residual magnetism, scientists found that when the particle size of ferromagnetic materials is less than 10 nanometers (1nm=10-9m, referred to as 1 nanometer), magnetic fluids exhibit superparamagnetism, meaning there is no residual magnetism. Under the action of a magnetic field, nano magnetic fluids also exhibit beautiful pinning phenomena. On the one hand, it intuitively displays the distribution of magnetic lines, and on the other hand, it has become an ideal material for electromagnetic wave shielding.
