The figure shows a rectangular circuit in a magnetic field that is out of the plane of the figure and given by $B=2\mathrm{.}00x^3{t}^5,$ with $B$ in teslas, $x$ in meters, and $t$ in seconds. The coordinates are $x_1=0\mathrm{.}600m,x_2=0\mathrm{.}800$ m $,$ and $y_1=0\mathrm{.}500m.$ The resistor has resistance $5\mathrm{.}00{10}^3$ and the wire has negligible resistance. What is the current $(A)$ through the circuit at $t=3\mathrm{.}00s?$
