Do Magnetic Field Lines Really Exist as Discrete Entities in Physics?

[temujin]

I always thougth the "dotted lines" illustrating the direction of a magnetic field were only a tool for vizualizing this direction...
Now I read that the definition of a weber equals 10^{8} field lines.

So does this mean that the field lines really exist as discrete lines along the direction of the field?

No, you were right the first time.
