Exhibition Name
Magnetic levitation light bulb
Science Behind It
The suspension of the light bulb utilizes magnetic levitation technology. The top of the bulb is equipped with a magnet, and the circular bracket directly above the bulb contains an electromagnet that generates a magnetic field when powered on. The magnetic field has an attraction to the magnet, and when the attraction is balanced with the weight of the light bulb, the light bulb can be suspended in the air. The suspended light bulb lights up from a distance, which may seem unbelievable, but it is actually because there is a transmitting coil installed below the bulb, and there is a receiving coil and LED light-emitting element inside the bulb. The transmitting coil emits electromagnetic waves, which generate current in the receiving coil through electromagnetic induction, thereby illuminating the light bulb. The wireless charging of smartphones adopts this principle. Magnetic levitation technology and wireless charging technology have been widely applied in our daily lives. What other devices in daily life use these technologies?
