Introduction that are deforming, and the resulting integral equations are different from those found in stationary systems. The formalism of integrating differential equations in the presence of motion is presented in Section B.4. The results are presented here essentially as postulates. 1.1.2a Magnetic Field Systems The integral forms of (1.1.1) to (1.1.3) and (1.1.5) are fH. dl = JJ n da, B - n da = 0, fJf - n da = 0, E'" dl = - d d B - n da.

The surfaces of integration S Fig. 1.1.1 (a) Surface S enclosed by the contour C, showing the right-handed relationship between the normal vector n and the line element dl; (b) surface S enclosing a volume V. The normal vector n is directed outward, as shown. A-PDF Split DEMO : Purchase from www.A-PDF.com to remove the watermark...
