Question

Are the field lines are reality​

Answer 1

Answer:

no field lines are not real they are just imaginary lines....

Answer 2

Answer:

Is it more accurate to imagine a field in a different manner. For instance, using grey-scale colour to imagine intensity. For instance, for a positive point charge, instead of imagining infinite lines emanating from the point, we image concentric shells around the charge, of infinitesimally thin thickness and all of a different grey-scale colour. So if we imagine black to be the maximum strength(intensity) and white to be 0 intensity, you would effectively imagine an infinitely large sphere whose colour change from white at infinity to black at the centre.
