»True bearing

»The Earth acts like a great spherical magnet and is surrounded by a magnetic field and the magnetic field is different in different places. The magnetic field changes with both location and time.

»You can also calculate the direction to the Qiblih from the BCCA web page. It provides the true bearing to the Qiblih, not the compass bearing.

»Some good books and a DVD about magnetism are:

»All compasses points in the directions of the horizontal component of the magnetic field where the compass is located, and not to any single point.

»Knowing the magnetic declination angle between true north and the horizontal trace of the magnetic field for your location allows us to correct the Bahá'í Compass for the magnetic field in your area.

»The Bahá'í Compass takes into consideration the magnetic declination to find the correct bearing to the Qiblih. When you buy from us you are requested to contact us in the future (10 year from purchase date) for a free adjustment (new map with coordinates) of the prayer direction. We are sure that our calculation is correct, +/- 1 degrees.
