This is a must-have book for your Electric fields and Magnetic fields (E&amp;M) class.  You need this book!  Get it!  Stop reading this, and get it!  If you're still reading this, here's some more aspects that will make you want this book.  If you've already gone through an E&amp;M class, but you want better understanding or just a review for whatever reason, get this book!  If you've never taken an E&amp;M class, but you have taken at least calc 1 and know about vectors, and you want to learn about E&amp;M, get this book!  It is BY FAR the best resource for getting started in E&amp;M.  It walks you through all of Maxwell's equations so expertly you'll have a sound foundation from which to build to even harder problems.  I guarantee this book is the best investment you'll make.  It's like reading an illustrated  transcript of a lecture from a professor who makes no mistakes, is exceptionally clear on his explanations, and who will guide you several times through the "boring" stuff to make sure you understand it from the context of each of Maxwell's equations.  It's a short, small book, too.  So, it won't be heavy to carry or take up too much space.  It pulls together all of the relevant topics to understanding each of Maxwell's equations, fully, that you'd have to thumb through many, many pages of a giant textbook to see.  It will open your eyes to the true meaning of each of Maxwell's equations and how to use them.  So, stop thinking about it, and GET THIS BOOK, NOW!!!
