Therefore, the sample offers the first solid measure of not only the strength of Earth's ancient magnetic field, but also of the timing of when the magnetic field originally appeared. "Extracting ...

The strength of the Earth’s magnetic field ranges between 25,000 and 65,000 nano-Tesla (nT) with values of 31-58,000 nT between the equator and 50 degrees latitude. The complexity of the ...

suggesting that such an event is directly linked to a dramatic change of the strength of Earth’s magnetic field. “This record reveals a substantial increase in the carbon-14 content of the ...

Would a dramatic change in the Earth's magnetic field affect ... robins into a steel chamber and reduced the strength of the ambient magnetic field by a third, the birds' flutterings were no ...

To investigate, describe and recall how the strength of the magnetic field depends on the current in the coil, the number of turns in the coil and the material used as the core of the coil.

A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

Pictures may enliven us, but other data, such as information about magnetic fields, add a huge amount to our understanding of ...

This, in turn, affects convection in the outer core—the dynamo-like process that generates the magnetic field that protects life on Earth from harmful cosmic rays. "Flow in the outer core drives ...
