A coil with $N=200$ turns, area $A=0.01\,m^2$, is placed in a uniform magnetic field that changes at $5\,T/s$. Calculate the induced EMF.

A solenoid with inductance $L=0.5\,H$ carries a current $I=4\,A$. Find the stored magnetic energy and the self-induced EMF if the current drops to zero in $0.01\,s$.
