Unformatted text preview: Slide Presentations for ECE 329, Slide Presentations for ECE 329, Introduction to Electromagnetic Fields Introduction to Electromagnetic Fields 3.1 Faradays Law and Ampres Circuital Law 3.13 Maxwells Equations in Differential Form Why differential form? Because for integral forms to be useful, an a priori knowledge of the behavior of the field to be computed is necessary. The problem is similar to the following: There is no unique solution to this. If y ( x ) dx = 2, what is y ( x )? 1 3.14 However, if, e.g., y ( x ) = Cx , then we can find y ( x ), since then On the other hand, suppose we have the following problem: Then y ( x ) = 2 x + C . Cx dx = 2 or C x 2 2 1 1 = 2 or C = 4 y ( x ) = 4 x . If dy dx = 2, what is y ? 3.15 FARADAYS LAW First consider the special case and apply the integral form to the rectangular path shown, in the limit that the rectangle shrinks to a point....
