Electric charge can be positive or negative (commonly carried by protons and electrons respectively, by convention). Like charges repel each other and unlike charges attract each other. Magnetic Flux Density. The grouping of H and M in Faraday's law and the flux continuity law makes it natural to define a new variable, the magnetic flux density B. This quantity plays a role that is analogous to that of the electric displacement flux density D defined by (6.2.14). Because there are no macroscopic quantities of monopoles of ...

Transcribed image text: A sphere of radius R has total charge Q. The volume charge density (C/m^3) within the sphere is p (r) = C/r^2. where C is a constant to be determined. The charge within a small volume dV is dq = pdV. The integral of pdV over the entire volume of the sphere is the total charge Q. Use this fact to determine the constant C ...An electric field (sometimes E-field) is the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them. It also refers to the physical field for a system of charged particles. Electric fields originate from electric charges and time-varying electric currents.…
