PPT-Electric Fields of Charge Distribution

Electrons on an insulator zoomed in Zoomed out difficult to see individual electrons smooth distribution of charge Like charge is smeared on the insulator   . In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir We offer the widest selection of horse fencing, electric fences, polytapes, energizers, polyrope, fencing accessories and other equine products. Physics 2415 Lecture 3. Michael Fowler, UVa. Today’s Topics. Continuous charge distributions: line of charge. Visualizing the field: lines of force. Electron moving in a field. Electric dipoles. Superposition. The Origin of Electricity. The electrical nature of matter comes from atomic structure. Nucleus. – . made up of . protons. and . neutrons. Most of the mass of the atom is contained in the nucleus. The electric force is one of the fundamental forces of nature. Controlled electricity is the cornerstone of our modern, technological society.. Chapter Goal: . To develop. a basic understanding of electric phenomena in terms of charges, forces, and fields.. .
