Okay so this is a pretty famous statement made to anyone who is introduced to the magnetic effects of electric current a.k.a. electromagnetism:
The relative strength of the magnetic field is shown by the degree of closeness of the field lines.
But it never made sense to me so I dropped the idea of studying e.m. deeply and just overviewed it superficially and somehow managed to pass the exam and moved to the next class. It's not until recently that I realised that we have the same chapter again in highschool graduation so I thought I'd better ask.
Yeah so we were told that field lines arise from north pole of a magnet and are closed curves going "into" the south pole (and run parallel to each other inside the magnet?) Then there's that statement. Out teacher drew small equal-area boxes showing that the one's "near" the poles contain in themselves more field lines than the ones farther apart(ring a bell?). But isn't it like every point in space has a field line passing through it? I mean there is exactly just as much "space" (or 2 dimensionally, area) in the other box as is in the first one. There can't be regions having no magnetic field in-between those lines? Isn't it kinda wrong?
