1. The problem statement, all variables and given/known data
Hi!
I really need help with finding time- dependent continuity equation for electron densities in the atmosphere. I've tried to solve it without any success. My question is if someone can give me a good link/link or equations that I can start with.

2. Relevant equations
See above. I already have the density of the electrons and I can calculate the magnetic force etc. But I need to see how the equation for this problem looks like. I assume that it should be something like
n_e(t)=n_e0*....
Thanks!

You need to define the problem, stating assumptions.
