Why fridge magnets don't break physics rules

Original: Answer to this # Electromagnetism_trivia : magnets on our fridge do not violate the impossibility of magnetic monopoles,

Astrophysicist Franco Vazza explains an electromagnetism trivia point: fridge magnets do not violate the impossibility of magnetic monopoles. They work because of a clever arrangement of the topology of magnetic fields from many smaller magnetic domains assembled together. He notes that 52% of respondents to his poll answered the question correctly, and the explanation is drawing attention from physics enthusiasts.

Why now: An accessible physics explanation is circulating and engaging people interested in electromagnetism.
