A rectangular conducting loop of resistance \(R\) has width \(a\) and height \(b\). The loop is pulled at constant speed \(v\) into a region where a uniform magnetic field varies with time as \(B(t)=B_{0}e^{-t/\tau}\). The loop starts to enter the field at \(t=0\) with its leading edge just touching the field region. (a) Derive an expression for the induced emf \(\mathcal{E}(t)\) while the loop is partially inside the field (i.e., for \(0
