Magnets and Electromagnetism

Some 200 years ago, nobody knew about the connection between electricity and magnetism. Now you're reading this on a computer, as perhaps a plane flies overhead, music plays in the background, and satellites send you information from space.... The modern world exists because scientists figured out the rules of electromagnetism and put them to work.
