Compasses and sunlight

Compass needles float on still water, they both point north, but they don't move north, why is that?

If one assumes that Earth's magnetic pole at the North Pole causes a compass to point north, then it will also cause a floating compass to move north.

The fact is that the compass points in a direction perpendicular to the weak westward current around the Earth caused by moving sunlight energy, not the Earth's supposed magnetic field.

This weak westward current becomes stronger as it approaches the poles, due to the smaller circumference that produces auroras at night. the smaller circumference that produces auroras at night.
