The magnetic field in a region is given by $\displaystyle \overrightarrow{\mathrm{B}}=\mathrm{B}_{\mathrm{o}}\left(\frac{x}{\mathrm{a}}\right) \hat{k}$. A square loop of side d is placed with its edges along the $\displaystyle x$ and $\displaystyle y$ axes. The loop is moved with a constant velocity $\displaystyle \vec{v}=v_{\mathrm{o}} \hat{\boldsymbol{i}}$. The emf induced in the loop is :
