Ferrofluid
★Exhibit Content: Morphological changes of magnetic fluid under the action of a magnetic field ★Interaction: Electromechanical interaction ★Operation: Move the magnet up and down to observe the phenomenon of the magnetic fluid. Press the "Start" button or long-press the "External Sound Source" button to observe the phenomenon of the magnetic fluid. ★Exhibit Description: The exhibit consists of guide posts, a magnetic fluid container, a magnetic rod, a base plate, a magnetic fluid speaker, etc., and is divided into two demonstration units: on the left, the shape of the magnetic fluid is controlled by moving a magnet; on the right, an electromagnetic speaker changes the magnetic field with music, making the magnetic fluid present dynamic shapes, intuitively demonstrating the laws of the magnetic field's effect on magnetic fluid. The exhibit consists of guide posts, a magnetic fluid container, a magnetic rod, a base plate, a magnetic fluid speaker, etc. Left exhibit: In the center is a tube of magnetic fluid, with 3 magnets evenly distributed around it that can move up and down. As the magnets move up and down, the magnetic fluid changes accordingly. Right exhibit: After the speaker is powered on, the internal electromagnet exerts a strong attraction on the magnetic fluid, allowing the magnetic fluid to move on these electromagnets. During the attraction process, the magnet generates a magnetic field. As the music in the control system varies, the strength of the magnetic field also changes. At this time, the shape of the magnetic fluid changes with the magnetic field, combining into various shapes. ★Scientific Principle: Magnetic fluid, also called magnetic liquid, is a stable colloidal solution formed by highly uniformly dispersing nano-sized magnetic particles in a carrier liquid with the help of a surfactant. Under the action of gravity, centrifugal force, and magnetic field force, it neither coagulates nor precipitates. It is a new type of functional material that possesses both the properties of magnetic materials and the fluidity of liquids.
