Ferrofluid Dance
★Exhibit Content: Characteristics of magnetic fluid and principles of electromagnetic control ★Interaction: Electromechanical interaction ★Operation: Visitors press the button to power on and watch the magnetic fluid shapes change with the music. ★Exhibit Description: The exhibit consists of a curved console, a matrix of magnetic fluid bottles, a bottom light box, an electromagnet array, an audio acquisition module, and a control system. It is a recommended exhibit from the PopsciCat Exhibit Store. On the tabletop, multiple glass bottles containing magnetic fluid are arranged in a matrix, each with a dedicated electromagnet underneath, paired with bottom backlighting. After visitors press the start button, the system begins operation, audio signals are transmitted to the control module, driving each electromagnet to change magnetic field strength in real time. The magnetic fluid in the bottles dances to the rhythm of the music, and with the lighting, the changes in magnetic fluid shape become more intuitive, providing visitors with a highly impactful visual experience. ★Scientific Principle: Magnetic fluid is a stable colloid formed by dispersing nano-sized magnetic particles in a base liquid, combining both the fluidity of a liquid and the magnetization properties of magnetic materials. When an electromagnet generates an external magnetic field, the magnetic particles inside the colloid quickly align along the direction of the magnetic field, causing the surface of the magnetic fluid to form a spiky special shape. As the magnetic field strength changes dynamically with the music audio, the shape of the magnetic fluid also changes synchronously; once the magnetic field is removed, the magnetic particles return to a dispersed state, and the magnetic fluid reverts to a smooth liquid, intuitively demonstrating the regulatory effect of electromagnetic action on special fluids.
