So your point is that every time they mention North Pole they don't necessarily mention "magnetic"? I think you're kind of grasping at straws here, it's a TV show written by people who probably aren't Physics grads (though I'm sure some of the script reviewers are). Really would it have added anything to the episode if they'd specifically said "Magnetic North Pole" every single time they mentioned the trip? Personally I don't think so, in fact it probably would have become kinda annoying. 206.47.249.251
