Exhibit Summary
Magnetic levitation light bulbs is a Electromechanical interaction interactive exhibit in the Electromagnetism category, designed for science centers, children’s museums, discovery centers, STEM learning centers and family entertainment centers. Built as a hands-on, mechanical & electromechanical display, it turns an abstract scientific concept into direct, interactive visitor exploration, and is engineered for durable, low-maintenance, high-traffic gallery use.
Scientific Principle
Magnetic levitation light bulbs mainly use the characteristics of magnets that "same sexes repel each other and opposite sexes attract each other", so that the light bulbs have the ability to resist gravity. At the same time, the changes in the magnetic field position of the light bulbs are sensed via magnetic field sensitive elements, and the current via the excitation coil is controlled to adjust the magnetic field, so that the magnetic force received by the light bulbs reaches a balance with its own weight, and the light bulbs are smoothly "suspended" in the air. The light bulb uses the concept of electromagnetic induction. Electromagnetic coils are installed in the bracket and the bulb respectively. The coil in the bracket is connected to the alternating current, and the coil in the bulb generates an induced current, which lights up the
Operation
exhibition item in the bulb. The exhibition item is composed of an electromagnetic suspension unit, a bracket and a bulb. When the start button is pressed, the tray in the glass cover will drive the bulb upward to a predetermined height, and the bulb will slowly float under the gravity of the electromagnetic levitation unit on the top. After the bulb is suspended smoothly, the bracket will automatically fall down, while the bulb will remain suspended. At this time, press the light bulb switch to light up the suspended light bulb, creating a better display effect. Press the start button and watch the bulb change.
