A semicircular conducting metallic loop of radius R is moving in x-y plane in a region of uniform magnetic field given by $\overrightarrow{B}={\text{B}}_{\text{0}}\left[\hat{i}+2\hat{j}+3\hat{k}\right]$ with velocity $\overrightarrow{V}={\text{V}}_{\text{0}}\hat{i}$ as shown in diagram. Then

$\overline{B}={\text{B}}_{\text{0}}\left[\hat{i}+2\hat{j}+3\hat{k}\right]$

$\overline{l}=2\text{r}\frac{1}{2}\hat{i}+2\text{r}\frac{\sqrt{3}}{2}\hat{j}$

$=\text{r}\hat{i}+\text{r}\sqrt{3}\hat{j}$

From$\text{E}=\left(\overline{V}\times \overline{B}\right).\overline{l}$

$\text{E}=3\sqrt{3}{\text{V}}_{\text{0}}{\text{B}}_{\text{0}}\text{R}$

Look at component$\text{3}\hat{k}$  in the magnetic field C will be at lower potential and A will be at higher potential
