Are electric field lines and electric flux the same thing?

Click For Summary
SUMMARY

Electric field lines and electric flux are distinct concepts in electromagnetism. Electric field lines represent the direction and strength of an electric field, while electric flux quantifies the number of field lines passing through a given surface. Electric flux is calculated by taking the dot product of the electric field at each point on the surface and integrating this over the surface area. Both electric flux and magnetic flux are scalar quantities, despite the vector nature of electric field lines.

PREREQUISITES
  • Understanding of electric fields and their representation

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
