Electrical and magnetic forces are so much a part of our everyday lives, that we don’t often think about how they work or how they are related. Before digital music players and eBook readers were commonplace, though, scientists put a lot of effort into discovering just what these forces were and how to harness their energy in ways that would make life easier. Through their experimentation, they discovered the connection between electrical and magnetic forces. They found ways to bring electricity to people who wanted it. Today, we benefit from these discoveries, but there are always new things to discover! Whether you try the experiments and activities in this book for fun or for a science fair project, you’ll get an up-close look at the forces of electricity and magnetism. Enjoy each of the shocking activities in this book as you discover the pull of science!
Describes what electricity is and how it is generated, stored, and used; explains what magnets are and how magnetism works; and discusses how electricity can be used to create magnets.
This is an undergraduate textbook on the physics of electricity, magnetism, and electromagnetic fields and waves. It is written mainly with the physics student in mind, although it will also be of use to students of electrical and electronic engineering. The approach is concise but clear, and the authors have assumed that the reader will be familiar with the basic phenomena. The theory, however, is set out in a completely self-contained and coherent way and developed to the point where the reader can appreciate the beauty and coherence of the Maxwell equations. Throughout, the authors stress the relationships between microscopic structure of matter and the observed macroscopic electric and magnetic fields. The applications cover a wide range of topics, and each chapter ends with a set of problems with answers.
Rereko is just your average high-school girl from Electopia, the land of electricity, but she's totally failed her final electricity exam! Now she has to go to summer school on Earth. And this time, she has to pass. Luckily, her ever-patient tutor Hikaru is there to help. Join them in the pages of The Manga Guide to Electricity as Rereko examines everyday electrical devices like flashlights, heaters, and circuit breakers, and learns the meaning of abstract concepts like voltage, potential, current, resistance, conductivity, and electrostatic force. The real-world examples that you'll find in The Manga Guide to Electricity will teach you: –What electricity is, how it works, how it's created, and how it can be used –The relationship between voltage, current, and resistance (Ohm's law) –Key electrical concepts like inductance and capacitance –How complicated components like transformers, semiconductors, diodes, and transistors work –How electricity produces heat and the relationship between current and magnetic fields If thinking about how electricity works really fries your brain, let The Manga Guide to Electricity teach you all things electrical in a shockingly fun way.
Unlock the secrets of circuits, batteries, and magnets! Learn all about current, static charges, motors, and more! All you need are some common household materials. If you are interested in competing in a science fair, you can get many great ideas that will help you create a unique, award-winning science project.
In this illustrated introduction to electricity and magnetism, Gill Arbuthnott explains the history of electricity, how it gets from its original source to your plug socket and what might happen in the future.
