When you think of “generating electricity,” do you imagine massive dams or giant power plants? In reality, the same mechanism used in the heart of a power plant is hidden inside tiny toys that fit in the palm of your hand. Today, I’m going to introduce a surprising experiment that uses a simple motor\u2014the kind found in Mini 4WD cars and hobby kits\u2014to generate electricity in an instant. The moment that small light bulb flickers to life like magic, you will witness the scientific truth of energy transformation!<\/p>\n

Are Motors and Generators Twins?<\/h3>\n

I previously visited an exhibit on generators at the National Museum of Nature and Science. The internal structure was clearly visible: when you turn the handle, a magnet in the center spins rapidly. Surrounding it are tightly wound coils. As the magnet moves, the magnetic flux<\/b> passing through the coils changes, and you can see exactly how much electricity is being produced.<\/p>\n
