WebEarth’s magnetic field is about 0.5 G [on the surface].” “…[T]he interplanetary magnetic field has the value of 5 nT.” “A magnetic field exerts pressure on the material producing it. At 100 T, the pressure [would be] in the range of 100,000 atmospheres or nearly 1.5 million pounds per square inch.” WebThis technique of mapping differences in the magnetic field from place to place is a standard one on Earth and is used extensively in prospecting. Many ore bodies cause anomalies in the Earth's magnetic field. Thus, if at a particular place we expect the magnetic field to be 40,000 nT and it is 36,000 nT, then the anomaly is 4,000 nT.
