Question
An infinitely long, DC current (I4) carrying wire is oriented along the z-axis as
shown in Fig. 1. As illustrated in parts (a)-(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.
