Magnetic field, a vector field in the neighborhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to lin
dynamo theory, geophysical theory that explains the origin of Earth’s main magnetic field in terms of a self-exciting (or self-sustaining) dynamo. In this dynamo mechanism, fluid motion in Earth’s outer core moves conducting material (liquid iron) across an already existing weak magnetic field...
magnetic field of 45.5 tesla—the highest field achieved so far, to our knowledge. The magnet uses a conductor tape coated with REBCO (REBa2Cu3Ox, where RE = Y, Gd) on a 30-micrometre-thick substrate3, making the coil highly compact and capable of operating at the very high winding ...
Tesla is the unit of measurement for magnetic field strength. The strength of a magnetic field is measured in teslas, a unit named after Nikola Tesla. It quantifies the concentration of magnetic flux in a given area. Understanding and measuring the magnetic field strength is crucial in ...
The Earth's magnetic field has not been mined as a source of energy for electrical power. With average field strength of .00005 Tesla around the world it is easy to understand why it has been overlooked. A disruptive technology is needed to mine the Earth's magnetic field as a power ...
The new device hits a sample with a 30 millitesla magnetic field, about 100 times weaker than is normally used in MRI. The device then uses a 46 microtesla magnetic field—about the same as the Earth’s magnetic field—to capture images of the sample. The first target for the device wa...
Definition Core field . The main part of the geomagnetic field, caused by dynamo action in the Earth's fluid outer core. Crustal field . The magnetic field contribution caused by (permanent or remnant) magnetized material in the Earth's crust. Internal sources . Magnetic field contributions caus...
All living organisms on the earth have been exposed to the geomagnetic field(GMF,~50μT),a nature component of the habitability environment,throughout the evolutionary history.However,the environmental magnetic field(MF)in space decreases geometrically with the distance from the ground.The MF magnitud...
The main contribution of this paper is the derivation of formulas for these problems. Comparison between data and theory indicates that the magnitude of the toroidal magnetic field (T20) has to be as large as 250 T (tesla) to explain the data. There are, however, some inconsistencies among ...
