Earth magnetic field strength vs altitude
Detection The Earth's magnetic field strength was measured by Carl Friedrich Gauss in 1832 and has been repeatedly measured since then, showing a relative decay of about 10% over the last 150 years. The Magsat satellite and later satellites have used 3-axis vector magnetometers to probe the 3-D structure of … See more Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the See more At any location, the Earth's magnetic field can be represented by a three-dimensional vector. A typical procedure for measuring its direction is to use a compass to determine the direction of magnetic North. Its angle relative to true North is the … See more Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind. This is a stream of charged particles … See more Earth's core and the geodynamo The Earth's magnetic field is believed to be generated by electric currents in the conductive iron alloys of its core, created by convection … See more Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are … See more Short-term variations The geomagnetic field changes on time scales from milliseconds to millions of years. Shorter time … See more Animals, including birds and turtles, can detect the Earth's magnetic field, and use the field to navigate during migration.
