the magnetic field lines you see are a not a demonstration of a lines in the magnetic field. Magnetic fields are continuous, and do not have discrete lines."
Magnetic fields are continuous in what sense? mathematically continuous or some other sense that has not been stated?
We have not seen anything continuous in our physical reality/this universe yet.
also who and by what principle/fact/logic/data one can state:"Magnetic fields are continuous, and do not have discrete lines" ? without defining a) what is meant by continuous?
b)How that conclusion came to be? and why did he/she stop there? they should have also added "God is Love" it just blends right in.

I think you two are mistaking "conceptual" for "imaginary".
The mathematical "real line" is itself a conceptual construct.
Humans do not have the cognitive machinery to sense a point/line/circle. Without defining what is meant by real arguing over what is not real ( imaginary ) is meaningless.
There are no lines there that one can be seen/sensed/ measured on it's own, instead there is how the iron fillings/plasma align that makes our primate brain see lines. This is just the Machs principle that it is meaningless to talk about the distance from earth to the moon without moon being there.
Please someone reply with an example of a "real line", e.g. is the line I draw on the paper a real line? or is it just the difference on reflection from paper that makes my brain to interpret it as "a line"?
What you are arguing over is not physics but meaning. If you can gather some magnetic field lines and put them in vase, water them and sell them for a buck then they are more real. There is no "real flower", just instances of the concept of flower, it is your mind that simplifies your view so you can hold onto a "real flower".
