How magnets work in terms of a school disco
A magnet is essentially just a Year 9 school disco where all the iron filings are desperately trying to find a dance partner.
In this scenario, every atom is an excitable teenager, and magnetism is the invisible social pressure forcing them to align in the same direction. When electrons line up, they create a magnetic field that acts like the smell of Lynx Africa in a cramped gymnasium. The two poles are the only two types of people in the hall: the ones who are dying to dance and the ones who are aggressively pretending they don't exist. If you bring two north poles together, it is like two lads from the rugby team being asked to slow dance to Ed Sheeran, resulting in an immediate, physics-defying repulsion that clears the floor.
Conversely, a north pole and a south pole will snap together with the desperate intensity of two people who have just realised the theme of the night is 80s power ballads. This attraction is strictly limited to iron, nickel and cobalt, meaning that wood, plastic and aluminium are the geography teachers standing in the corner, blissfully unbothered by the chaos. These materials have electrons that are far too sensible to get involved in the magnetic drama, preferring to stay at the buffet table eating lukewarm sausage rolls rather than participating in the field lines.
Where the analogy breaks downActual magnets do not eventually get embarrassed and stop interacting after a disciplinary meeting with the headmaster.
