Franklin Strait
Being close to the magnetic north pole means that magnetic compasses don’t work. The needles try to point down. I’m not sure where the magnetic north pole is now (the magnetic poles move), but it is within several hundred miles of us. Issuma’s compass stopped working in NW Baffin Bay. Nautical charts have compass roses on them, where a compass dial in relation to True North and inside it, a smaller compass dial in relation to Magnetic North. The picture is from a Canadian arctic chart.
