Descriere magazin:
ScienceWiz(R) Inventions: This multi-award winning book and kit uses everyday materials to build A spinning motor A clicking telegraph A light-flashing generator A real radio. The use of simple materials (no plastic required) helps to demystify the why as well as the how. The step by step, fully-illustrated, 40 page book makes the projects very doable and the explanations easy to understand. Imagine building a working radio using only aluminum foil, wire and a diode. That\'s it. No battery required. Now make a spinning motor using only paper clips, a magnet, a bit of wire and a battery. Light a bulb by spinning a coil of wire next to a bar magnet. Make a telegraph click and send coded messages to a friend using just two paper clips, a nail, wire and a battery. Every day materials, indeed! These are all inventions with coils . With these inventions you can explore the discoveries of Michael Faraday and Nikola Tesla, two scientists whose work led to the creation of the electrical grid.
