Definition of Magnetic Declination,Inclination

  1. Apr 2, 2013 #1
    I wish to know what exactly magnetic declination and inclination means. I used to feel that angle of declination was constant throughout the Earth equalling≈11.3°.But, it apparently isn't.
    Then, why is so much significance attached to 11.3° if it is not universally constant?
