In studying this chapter you should aim to understand the basic concepts of electric charge and field and their connections. Most of the material provides illustrations which should help you to acquire that understanding. To test whether you have understood the concepts see if you can describe and explain the applications in your own words.
Introduction
The natural world provides precious few clues to the ubiquity of electromagnetism. The properties of rubbed amber and the magnetism of lodestone were little more than curiosities until the 17th century. The elucidation of the nature of lightning and the recognition of light as electromagnetic radiation were even more recent. Yet our world is governed by electromagnetic interactions. All chemical bonds, the strength and weakness of materials, light, the influences that form and control living things are all aspects of electromagnetism. Indeed, only three other types of fundamental force are known: the weak force, the strong force and gravity.
Of these forces the first two, which are purely nuclear forces, are effective only over distances of less than 10-12!m - that is smaller than an atom. They are associated with radioactivity, but otherwise are of no consequence in chemistry and biology. Gravity is such a feeble force that it matters only in interactions involving bodies of ‘astronomical’ mass and is negligible in interactions between small things. Apart from the earth 's gravitational pull, every
force that you
