Q11. How is a compass direction measured?
(Discuss Earth's magnetic field and body forces.)
Q12. What is magnetic declination?
Q13. Why is magnetic declination important?
Q14. How do you determine the declination of a given location at a given time?
The most accurate way to find the declination of a given point on Earth is to use the declination calculator maintained by the National Geophysical Data Center (NGDC), accessible on the web at http://www.ngdc.noaa.gov/geomagmodels/Declination.jsp. Directions for using the calculator are available at http://www.ngdc.noaa.gov/geomag/magfield.shtml
Determine the location of the Baylor Science Center using a GPS receiver*, and then use the NGDC declination calculator to determine the magnetic declination today at the BSC.
