Easy electric start circuits with motor and meter

How do you build an electric code lock, how high does the propeller climb at full power and how do I generate electricity with magnets? How does electrical engineering work in everyday life? In sixty experiments on physical phenomena such as current and voltage, electricity and magnetism, children playfully immerse themselves in the world of electrical engineering.
With the child-friendly easy-click system and precise construction plans, the young researchers carry out the experiments themselves: They take the first measurements, experiment with an electric motor, build alarm systems with relays and learn step by step what is possible with electricity. The instructions clearly show how the circuits are set up and how they are used in simple everyday objects such as doorbells and complex devices such as MRI scanners.
A great beginner's course on electricity and magnetism!
