In the given figure the magnetic flux through the loop increases according to the relation $\displaystyle \phi_\beta(t)=10 t^2+20 t$, where $\displaystyle \phi_\beta$ is in milliwebers and $\displaystyle t$ is in seconds. The magnitude of current through $\displaystyle \mathrm{R}=2 \Omega$ resistor at $\displaystyle t=5 \mathrm{~s}$ is \_\_\_\_ mA.
