A uniform magnetic field is applied to a circular loop wire with a radius of $5\mathrm{.}0$ cm and a resistance of $0\mathrm{.}20$ in a direction perpendicular to the plane formed by the circular loop. If the strength of the magnetic field changes with time in the form B $=5\mathrm{.}0$e$-$t T$,$ how many mA is the current induced in this circular wire at t $=2\mathrm{.}0$ s$?($to the nearest whole number$)$
