The Magsat satellite and later satellites have used 3-axis vector magnetometers to probe the 3-D structure of the … Visa mer 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 Visa mer 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 declination (D) or … Visa mer 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 ionosphere (ionospheric dynamo region) and magnetosphere, and … Visa mer Animals, including birds and turtles, can detect the Earth's magnetic field, and use the field to navigate during migration.

The details of the theory are rather complex. In summary, it states that the Earth’s magnetic field is generated by movements stirred up by the Earth’s rotation known as “convection currents” in the outer core, which is liquid and, because it is made out of iron, is a good ... church of christ country music starsThe kinematic approximation becomes invalid when the magnetic field becomes strong enough to affect the fluid motions. In that case the velocity field becomes affected by the Lorentz force, and so the induction equation is no longer linear in the magnetic field. In most cases this leads to a quenching of the amplitude of the dynamo. Such dynamos are sometimes also referred to as hydromagnetic dynamos. Virtually all dynamos in astrophysics and geophysics are hydromagnet… dewalt handheld two way radiosWebbWorldbook Encyclopedia, vol. 13. 1995.
