You couldn't - you could get it to point at Magnetic North & South at the same time if you stood in the right spot

ahh - good point - a magnetic case you argue there mofra

Trust some with a natural deviation to pick that mistake lol.

PS the previous one was Bluff in SI NZ

PS you're obviously onto it, but the point would point straight down the magnetic axis if you stood at the magnetic north pole - and that would be close enough to going through both poles.

ps deviation sometimes called declination etc

PS They say that Magnetic Island off Townsville had a signific effect on Cook's first navigation of the east coast around there - but he was too smart not to twig to what the problem was

not obvious this one ...
how many times does the earth rotate in an average year (i.e averaging over 4 years including one leap year) ?

a) 364.25
b) 365.25
c) 366.25?

(by rotate I mean relative to 'Aries' - i.e. relative to the stars)
