... difference ΔV. It is then deflected by a uniform magnetic field (perpendicular to the ion’s velocity) into a semicircle of radius R. Now a doubly charged ion of mass m’ is accelerated through the same potential difference and deflected by the same magnetic field into a semicircle of radius R’ = 2R. ...

... b) The Pacific plate is moving northeast over a hotspot in Earth's mantle that continually produces new volcanism directly above it. c) The island chain results from the subduction of one oceanic plate under another. As the subducting plate sinks into the mantle and melts, magma rises, producing vol ...

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.
