Summary of electrostatic relations between electric potential, electric field and charge density. Here, r = x − x ′ {\displaystyle \mathbf {r} =\mathbf {x} -\mathbf {x'} } . If the electric field in a system can be assumed to result from static charges, that is, a system that exhibits no significant time-varying magnetic fields, the system ...
Classical Electrodynamics is a textbook written by theoretical particle and nuclear physicist John David Jackson.The book originated as lecture notes that Jackson prepared for teaching graduate-level electromagnetism first at McGill University and then at the University of Illinois at Urbana-Champaign.

The first chapter offers a valuable review of vector calculus, which is essential for understanding this subject. While most other authors, including those aimed at a more advanced audience, denote the distance from the source point to the field point by | x − x ′ | {\displaystyle |\mathbf {x} -\mathbf {x} '|} , Griffiths uses a script r ...
Electric potential energy is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system.
The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics.The name originates from the replacement of certain elements in the original layout with fictitious charges, which replicates the boundary conditions of the problem (see Dirichlet boundary conditions or Neumann boundary conditions).
The most common description of the electromagnetic field uses two three-dimensional vector fields called the electric field and the magnetic field.These vector fields each have a value defined at every point of space and time and are thus often regarded as functions of the space and time coordinates.
Joseph Lynskey, who miraculously survived being pushed onto the path of a subway train on New Year's Eve, broke his silence to thank those who aided him.
