Electromagnetics
Electromagnetism defined as "magnetism produced by an electric current". In other words it is the electricity part of what holds ourselves and every bit of matter in the universe together. This source of universal "glue" is found within atoms themselves. As the name sounds, there are two different forces within electromagnetism - the electric force and the magnetic force. Before the early part of the last century, scientist studied electricity and magnetism as different sciences. No one knew the connection between them. Electromagnetism was found almost by accident, that a" flow of electric current (a movement of electric
The most common forms of electromagnetic radiation are radio waves and light waves. Nearly 900 years ago, the Chinese discovered the natural permanent magnet - lodestone or magnetite. Electromagnetism - "caused by passing an electric current through a conductor such as metal wire"Both of these magnetic fields, once created, is exactly the same. al charge) creates a magnetic force" to use the words of Jack R. It may be shown that electromagnetic waves transport energy as well as carry momentum. His work was the first of many other experiments and "theoretical" research that many other well known scientists have used his works with there own experiments. From this they then created a magnetic compass. I will first explain the magnetic force in electromagnetism. To the Chinese in that time, magnetic force seemed to be magic, but in the twentieth century we use magnetic fields everyday. In such things as the refrigerator, the washing machine, the dryer, and the vacuum cleaner all have electric motors. White, author of The hidden World of Forces. After playing around with this rock they discovered that when floating on a piece of wood it would always point itself north. It is impossible for a wave with just one or the other to exist. How it is produced and charged by currents, and how it is distributed in space and time. Maxwell presented a set of equations that completely describe the electromagnetic field.
