Мотори и генератори

A set of 25 science experiments featuring a hand-cranked electric generator. Build your own electric motor! Generate electricity to power your lights! Includes a hand-cranked electric generator! Electric motors and generators are in countless devices, appliances, and vehicles we use every day. They are a fundamental technology in our modern world. With this set, you can conduct 25 experiments to learn how an electric motor converts electrical energy into motion and how an electric generator does the opposite - converts motion into electricity. The electric motor is made of clear plastic so you can see how the internal components work. Insert a battery and learn how a motor works. Then reconfigure the device to run in reverse as a hand-cranked electric generator. Experiment with magnets to learn more about the strength of magnetism and how magnetic fields affect electric current. Build simple circuits consisting of a motor or generator, wires, and a light bulb to learn about the flow of electricity. Learn more about gears and drivetrains and how they work efficiently to convert kinetic energy into electrical energy and vice versa. Includes a 48-page, full-color instruction manual in Bulgarian. Dimensions: 13 x 20.8 x 6 cm. Age: 8+ years
