## Electric Field And Magnetic Field Become The Electromagnetic Field

The 4-vector concept also allows us to condense the mathematics of electromagnetics, and reveals the true nature of the electromagnetic field. By combining the magnetic vector potential with voltage into a four vector: A = [Ax,Ay,Az,V/c], a single electromagnetic potential is formed. Using this 4-potential, the electric and magnetic fields combine to form a single electromagnetic field, which can be represented by a mathematical object called a tensor. In the mathematical system called Clifford geometry, the electromagnetic field can be written simply as F = E + icB, where i = V—1. Within this mathematical system, Maxwell's equations condense to a single equation! (Refer to Baylis [1999].)

## Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
