A few trivia items from the BBC QI elves: "Jupiter’s magnetic field has two south poles." "Roughly every 11 years, the magnetic field of the sun reverses, north becomes south, and south becomes north. The same thing happens on Earth, but only about once every 300,000 years." "The magnetic North Pole is moving about 55km per year at the moment. Last year it wandered over the international dateline and ended up in the Eastern hemisphere." https://twitter.com/qikipedia/status/1082639057556029443 https://twitter.com/qikipedia/status/1082639057556029443 https://twitter.com/qikipedia/status/1043545462186356737 https://twitter.com/qikipedia/status/1043545462186356737 https://twitter.com/qikipedia/status/1085145132591124481 https://twitter.com/qikipedia/status/1085145132591124481
