@attie Well yes, that's why your north pole of your compass is attracted to it.

(Oddly I've just been reading a 1920s physics text book that made the same point)

Toot

@penguin42 I don't know why, but I always thought that compasses had the poles mis-marked, so that they'd "Point North" which was "Pointing to the North Pole" (i.e: the South Pole, but that detail was hidden), not "Pointing to the 'North Pole', which is magnetically the South Pole" 😵
