Introduction
Welcome to Magnet Secrets. Magnetic fields are amazing. They are the invisible energy manifestation projected from a magnet. Just moving a copper wire through a magnetic field generates electricity in the wire. But the opposite is also true. Running electricity through a wire that is placed in a magnetic field forces the wire to move. These three forces, magnetism, electricity, and physical motion, are bound together to make electric motors and electric generators do what they do. This simple set of discoveries from the 1830's has evolved to make the whole "modern era" possible. Currently, magnets and magnetic fields are used in hundreds of technologies. The list is very long, but a few of the more obvious examples including audio and video recording, computer memory, navigation systems (including the compass), electric power generation, electric cars, and holding notes to your refrigerator! What is common to all of these applications is that they take advantage of the large physical or electrical force
