Webthe Earth’s outer core. The magnetic field strength increases from 25,000 nanoteslas (nT) at the magnetic equator to 70,000 nT at the mag-netic poles. (One nanotesla equals 1 gamma, and 105 gammas equals 1 oersted.) The Earth’s mag-netic field changes in intensity and direction slowly over time. Like all dipole magnets, the Earth has a mag- WebThis technique of mapping differences in the magnetic field from place to place is a standard one on Earth and is used extensively in prospecting. Many ore bodies cause anomalies in the Earth's magnetic field. Thus, if at a particular place we expect the magnetic field to be 40,000 nT and it is 36,000 nT, then the anomaly is 4,000 nT. birch bark light switch covers https://cervidology.com
