I would suggest you really do not know what you are talking about except from reading things on google search when you need an answer. I suggest you are a spod and are not really serious about science. Magnetic field lines are not hard to observe, we all have done the iron filings field line test on a magnet. The North polarity field lines curve back towards the south polarity fields and vice versus, the spaces between the field lines are caused by the likewise polarity of the field line repulsing itself. Quite clearly you know very little about magnetic field lines.
