Power Generation Anchor

Mobile Science Museum · Electromagnetism

Operation: Hold the anchor with your hand, swing it to a 30–45° angle from the vertical, release it, and let the anchor swing freely while observing the changes in the indicator light. Function Overview: The exhibit consists of a display stand, an instruction sign, a support frame, an electromagnetic induction coil, an anchor model, and light-emitting diodes. Visitors hold the anchor with their hand, swing it to a 30–45° angle from the vertical, release it, and let the anchor swing freely. They will see the LED lights on the anchor flash and light up. Scientific Principle: The wonderful nature contains endless energy: light energy, electrical energy, thermal energy, mechanical energy, chemical energy, and so on. In this exhibit, a strong magnet cutting through a coil generates an induced current, which lights up the light-emitting diodes, thus achieving an interesting conversion among magnetism, electricity, and light.
