Static Fields and Potentials

Static Fields and Potentials describes two of the fundamental interactions in nature: gravity and electromagnetism. The book introduces the associated fields, potentials, and energies and explains the relationship among them. It shows how these interactions manifest themselves in different ways, from the formation of stars to the operation of thund
