$(23)$ A $40\mathrm{.}0-$cm$-$diameter coil consists of $30$ turns of circular copper wire $2\mathrm{.}2$ mm in

diameter. A uniform magnetic field, perpendicular to the plane of the coil, changes at a rate

of $3\mathrm{.}60\backslash$times $10^(-3)($T$)/($s$).$ What's the induced current in the loop? The resistivity of copper is

$\backslash$rho $\_($copper $)=1\mathrm{.}68\backslash$times $10^(-8)\backslash$Omega $*$m
