tech 😮 on Instagram: "This is how you can generate electricity using a magnet — no batteries needed. When a magnet moves through a coil of wire, it pushes electrons and creates a small electric current. It’s the same principle behind generators, bike dynamos, and even power plants. The amount of electricity you get depends on how strong the magnet is, how many times the wire is coiled, and how fast the magnet moves. Stronger magnets + faster motion = more power. Safety note: This doesn’t create
