alright you geeks...
who wants to explain lines of force (electric fields) to me?

what about them, you could spend ages on them.
electric field, is the force per charge
positive charges have a field going out from the center
go look up coulombs law kq/rr

i already have coulomb's law, and all that other stuff. what i want to know is that are lines of force just what you're drawing when you draw the field diagrams?

you may be drawing the force that 1 partical applys to another(coulombs law)
you may be drawing the flux, which is the field times area

if you see a particle with lines comming out of it most of the time its showing the electronic field which exerts forces on objects

Field lines are a way to visualize force. They are IMAGINARY, i.e. they do not exist (as far as we know). They are a concept to help people understand the electromagnetic force. For the electromagnetic force, field lines exit positive charge and enter negative charge. Their density is related to the strength, i.e. the closer the lines, the stronger the field -> more force. Therefore, the force close to a source or sink is greater than far away. Field lines always have a source and a sink.
