When the flow of charge is distributed throughout a three-dimensional region, we
describe it by the volume current density, J, defined as follows: Consider a "tube"
of infinitesimal cross section daħ, running parallel to the flow (Fig. 5.14).
Figure 5.15 Figure 5.16 Example 5.4 (a) A current / is uniformly distributed over a
wire of circular cross section, with radius a (Fig. 5.15). Find the volume current
density J. Solution: The area-perpendicular-to-flow is na , so J = / This was trivial
Problem 5.5 A current / flows down a wire of radius a. (a) If it is uniformly
distributed over the surface, what is the surface current density Kl (b) If it is
distributed in such a way that the volume current density is inversely proportional
to the ...

This is one of my all-time favorite science books! Does a BRILLIANT job of presenting the physics, and reviews the basic math (divergence, Stoke's Theorem, etc). This book is a MUST for anyone in ... Read full review
This is an exceptional standard book on engineering level Electricity and Magnetism
No other book in market stands against this book in competition. Almost all IIT s refer this textbook for 1st year Physics coarse.
