In 1886, Werner von Siemens discovered the dynamoelectric principle in Berlin. Due to the residual magnetism in the iron of the field magnets, an induction voltage is generated when the rod rotates. If a consumer is connected to the dynamo, current can now flow and the magnetic field of the electromagnets is strengthened.
This electric current, created by manually activating the dynamo, will lift the helicopter and make it fly. Interestingly, with so little current, the helicopter stays in the air. Have fun with the crank.
Warning: contains small parts that can be swallowed, not recommended for children under 3 years old.
