Earth’s magnetic field linked to changing orbit – Physics World

WebMar 28, 2002 · Earth’s magnetic field linked to changing orbit. 28 Mar 2002. Long-term fluctuations in the intensity and inclination of the Earth’s magnetic field could arise from … The inclination is defined locally for the magnetic field due to the Earth's core, and has a positive value if the field points below the horizontal (ie into the Earth). Here we show how to determine the value of at a given latitude, following the treatment given by Fowler. Outside Earth's core we consider Maxwell's equations in a vacuum, and where and the subscript denotes the core as the origin of these fields. The first means we can introduce the scalar poten… small homes for sale in houston

The inclination of the Earth's field is 90° (downwards) at the North Magnetic Pole and -90° (upwards) at the South Magnetic Pole. The two poles wander independently of each other and are not directly opposite each other on the globe. 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 … See more Short-term variations The geomagnetic field changes on time scales from milliseconds to millions of years. Shorter time scales mostly arise from currents in the … See more 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 … 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 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 … See more WebSaturn.
