PPT-Electrostatics Review Electric Fields

Electric Potential Energy Charges The fundamental rule at the base of all electrical phenomena is that like charges repel and opposite charges attract An object that has unequal numbers of electrons and protons is . 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 Field Structures . and Magnetic .

These graphs show the . electric potential outside . a uniformly charged plane (membrane) as a function of distance away from the plane.  Both curves represent measurements of electric field magnitude . Electric fields are created by . electric charges. . Any object with a charge has an electric field around it. Opposite charges attract each other; like charges repel. An electric field is a region in which a charge experiences a force. . Electrons on an insulator (zoomed in).. Zoomed out – difficult to “see” individual electrons . smooth distribution of charge..  Like charge is “smeared” on the insulator.  . - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -.
