The photo above is praised in Wikipedia by people who don't know it's a staged fake: Hidden CAPTCHA's are the most common site-breaking bugs on the internet Famous photo is fake See my video, with explanation in the text below it: So, yes, it's literally children who learned this wrong in childhood, and as adults they keep repeating it (wrong) while they're busy giving each other PhD's. This gross misunderstanding by the finest minds of the 21st century is almost identical to mistaking the rings of Saturn as "gravity lines". The "lines" would not exist without the iron influencing it. The iron filings bunch together and concentrate the magnetic field in a "line" pattern in the iron. The idea that magnetic fields have lines comes from the childhood demonstration of a magnet under a sheet of paper with iron filings on it. Anyone who uses that phrase does not know what they're talking about. Remember children, there is no such thing as a "magnetic field line". Stop teaching this to children, because it's wrong.
