A rectangular loop with sides of length $a=1\mathrm{.}40cm$ and $b=3\mathrm{.}00cm$ is placed near a wire that carries a current that varies as a function of time: $I_t=2\mathrm{.}09+1\mathrm{.}17t^2$ where the current is in Amperes and the time is in seconds. The distance from the straight wire to the closest side of the loop is $d=0\mathrm{.}220cm.$

What is the magnetic flux through the loop at time $t=2\mathrm{.}10$ seconds? $($Define positive flux into the page.$)$

$8\mathrm{.}68{10}^{-8}{T}^{**}{m}^2$

What is the induced e$.$m$.$f$.$ in the loop at time $t=2\mathrm{.}10$ seconds? $($Note that positive emf is clockwise.$)$

$-{6\mathrm{.}29}^{**}{10}^{-8}V$

Compute the rate of change of magnetic flux through the loop to get the e$.$m$.$f$..$
