Question

Can you have negative flux?

Answer 1

1. Electric flux is the measure of the flow of the electric field through a given area'
2. There are two types of flux, positive flux, and negative flux. The diagrams of these fluxes are shown below.
   
3. The electric flux is positive when electric lines emerge from a surface and negative when the same lines enter a surface.
4. Therefore, we can have negative flux.
