Magnetic field due to moving charge
 
\begin{aligned} & \mathbf{B}=\frac{\mu_0}{4 \pi} \frac{q v \sin \theta}{r^2} \\ & B=\frac{\mu_0}{4 \pi} \frac{\mathrm{ev} \sin (\pi / 2)}{r^2} \end{aligned}

 \begin{aligned} & \mathrm{~B}=10^{-7} \times \frac{1.6 \times 10^{-19} \times 6.76 \times 10^6}{\left(0.52 \times 10^{-10}\right)^2} \\ & \mathrm{~B}=40 \mathrm{~T} \end{aligned}
