An infinitely long, DC current (I,) carrying wire is oriented along the z-axis as shown in Fig. 1. As illustrated in parts (d)-(f), a square conductive loop in the y-z plane having a finite resistance R is moved/rotated as described in figure. For each of these cases, a. Is a nonzero electromotive force (Vemf) induced in the loop? If so, explain how it occurs and state what the type (transformer/motional) of emf that occurs. b. What is the corresponding direction of current flow in cases where a nonzero Vemf is found to occur in part a? Explain how the direction of current is found by virtue of Lenz's Law. (e) Rotate around center vertical axis (f) Rotate around center horizontal axis (d) move along -x
