... Magnetic fields obey the superposition principle, so the new magnetic field at each point will be the sum of the contributions from each bar magnet. The new magnet will contribute a magnetic field at point A which points to the left (into its south pole). This is in the same direction as the origina ...

... In the late 1950's, scientists mapped the present-day magnetic field generated by rocks on the floor of the Pacific Ocean. The volcanic rocks which make up the sea floor have magnetization because, as they cool, magnetic minerals within the rock align to the Earth's magnetic field. The intensity of ...

Lesson 3: Magnets
... It has two ends that are called magnetic poles. One end of the magnet’s poles is called the north seeking pole. This is because it tries to point north. The other pole of a magnet is called a south-seeking pole. This is because it always tries to point to the south. On the magnet the north seeking p ...

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.
