Electricity and MagnetismA text for the standard electro-magnetism course for students in physics and engineering. Treats requisite theory with extensive examples of real-world applications. Offers coverage of topics neglected in most texts at this level, such as macroscopic vs. microscopic properties of matter. Also features a shorter, more student-oriented presentaton of the material, larger problem sets, and thorough discussion of alternative solution methods. |
