Figure (38-E5) shows a square loop of side \( 5 \mathrm{~cm} \) being moved towards right at a constant speed of \( 1 \mathrm{~cm} / \mathrm{s} \). The front edge enters the \( 20 \mathrm{~cm} \) wide magnetic field at \( t=0 \). Find the emf induced in the loop at (a) \( t=2 \mathrm{~s} \),
(b) \( t=10 \mathrm{~s} \), (c) \( t=22 \mathrm{~s} \) and (d) \( t=30 \mathrm{~s} \).
\( 5 \mathrm{cmT} \longrightarrow \begin{array}{cccc}\longrightarrow & \times & \times \\ & \times & \times \\ \times & \times & \times \\ & \times & \times & \times \\ \times & \times & \times \\ & \times & \times\end{array} \)
\( \times \times \times \times \)
\( \begin{array}{cccc}\times \quad \times & \times & \times \\ \longmapsto & 20 & \mathrm{~cm} & \\ & & \end{array} \)
