Subject: Electromagnetic Field Theory

please mention each step involving in the solution.

Question No. 5 a) If \( B=B \overrightarrow{a_{z}} \), then prove that magnetic flux passing through hemisphere of radius \( \mathrm{r}=5 \mathrm{~cm} \) centered at the origin and bounded by the plane \( z=0 \) is equal to the magnetic flux passing through the disc. b) Explain the equation \( \nabla \cdot B=0 \)
