The magnetic field of [[Earth]] is directional nearly north-to-south, although slightly askance, meaning that "magnetic north" is not the same as "true north," and a person who is orienteering must take into account this change of declination, although it is truly only marginally relevant, unless you are close to either pole.<ref>Boy Scout Handbook.</ref> This field has been decaying at a rapid rate of about about 5% per century, which casts doubt on the theory that the [[Earth]] is billions of years old.<ref>K.L. McDonald and R.H. Gunst, 'An analysis of the earth’s magnetic field from 1835 to 1965,’ ESSA Technical Report, IER 46-IES 1, U.S. Govt. Printing Office, Washington, 1967.</ref> This decay suggests that, at some point, the poles will invert.

Scientists have speculated about the history of Earth's magnetic field. One group that makes use of the [[Bible]] as a resource for science suggests that the history of the Earth's magnetic field is as depicted to the right.<ref>http://www.answersingenesis.org/creation/v20/i2/magnetic.asp</ref>
