Yep...the Earth moves around it's magnetic poles...to be more precise it oscillates (some scientists have theorised that the poles actually reverse every few millenia). What this means is that the magnetic alignment changes every year. For SEN it's a 0.15% change but for AUH it's only 0.05%. Just depends where you are geographically!
