Hi Magnus:

The needles on a magnetic compass have a weight to counter the magnetic 
force in the vertical direction that otherwise would tilt the needle to 
the point that it would rub on the compass card or cover glass.  In N. 
California the magnetic field in the vertical direction is about twice 
the field in the horizontal plane.

Have Fun,

Brooke Clarke
