Exercise $6\mathrm{.}6$ An infinite wire carries a current I up the y$-$axis. To the right, in the

xy$-$plane, is a rectangular loop with one side of length L parallel to the wire and

at a distance a$,$ and the opposite side at a distance b $>$ a$.$ What is $($i$)$ the flux

penetrating the loop, and $($ii$)$ the emf E if the current in the wire changes at a rate

dI

dt $?$ Do the numbers for L $=0\mathrm{.}24$m$,$ b $=2$a$,$ dI

dt $=9\mathrm{.}6$ A
