Which of the following statements holds for the divergence of electric and magnetic flux densities?
-
- Both are zero
- These are zero for static densities but non zero for time varying densities
- It is zero for the electric flux density
- It is zero for the magnetic flux density
Correct Option: D
Divergence of magnetic field is always zero because magnetic flux makes always a closed path.
So ∇ .B = 0 (Maxwell's equation),
while divergence of electric field ∇ .E = | ||
ε0 |
