Hi
I have a hard time understanding what the curl really means in Maxwell's equations, for example in a steady-state you have
[tex]\nabla\times \textbf{E} = 0[/tex]
and in a time-varying field you have
[tex]\nabla\times \textbf{E} = -\frac{\partial \textbf{B}}{\partial t}[/tex]
The meaning of the divergence is like "outflow - inflow". I read that the curl is like the amount of rotation. But what does it means in this situation with the electric field? That electric field lines don't "rotate"/curve like for the magnetic field?
