Twenty-year study yields precise model of tectonic-plate
... The new model, dubbed MORVEL for "mid-ocean ridge velocities," is described in an extensive article available online and slated for the April issue of Geophysical Journal International. The work builds on the collaborators' 1990 paper on tectonic plate velocities that has been cited more than 2,000 ...

... André Ampere followed up on this discovery and found that two parallel wires carrying electric currents running the same direction attracted each other. This observation led to the creation of a solenoid or coil as shown in Figure 1. In the solenoid, the magnetic field created by a loop of wire carr ...

Solid State 2 – Homework 9 Use the Maxwell equation
... a) We can use the Helmholtz free energy F(B,T,N) for cases where the magnetic field B inside a material is constant. But when we set the external magnetic field constant, we need to minimize a different energy: X(H,T,N) . Write an expression for X and identify it with a thermodynamic energy you know ...

Magnetotellurics
Magnetotellurics (MT) is an electromagnetic geophysical method for inferring the earth's subsurface electrical conductivity from measurements of natural geomagnetic and geoelectric field variation at the Earth's surface. Investigation depth ranges from 300m below ground by recording higher frequencies down to 10,000m or deeper with long-period soundings. Developed in the USSR and France during the 1950s, MT is now an international academic discipline and is used in exploration surveys around the world. Commercial uses include hydrocarbon (oil and gas) exploration, geothermal exploration, mining exploration, as well as hydrocarbon and groundwater monitoring. Research applications include experimentation to further develop the MT technique, long-period deep crustal exploration, and earthquake precursor prediction research.
