Are electric field lines and electric flux the same thing?

    I don't believe they are because the field lines don't have a representation such as flux but I want to be sure. Also are flux lines a vector quantity?

    Flux is the density of field lines piercing a surface; to calculate it you take the dot product of the field at each point of the surface with the electric field at the same point; then integrate this over the given surface.

    Magnetic flux is found the same way.

    These are both scalar quantities.

    For magnetic flux see http://en.wikipedia.org/wiki/Magnetic_flux
