Ancient Homo sapiens may have benefited from sunscreen, tailored clothes and the use of caves during the shifting of the ...

Now, these structures act as time capsules, evidencing the strength of the magnetic field at various points in Earth’s development. An analysis of feldspar from southern Brazil revealed that 591 ...

A study by geophysicists from UC Berkeley and their Italian and French colleagues has shed new light on Earth's last major ... two intervals of low magnetic field strength. These fluctuations ...

The Earth's magnetic field quietly supports life on the planet and now, for the first time, its invisible powers have been used to create new nanoparticles and materials.

Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

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 ...

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.

Geophysicist Daniel Lathrop wants, among other things, to use it to predict when the Earth’s magnetic field will next reverse. Over the course of our planet’s history, the field has flipped ...

While shifting is not a rare occurrence, the pole is moving both faster and differently than it was before, raising questions about the planet's magnetic field. If the Earth's field is disrupted ...

A second experiment can be carried out to investigate how the strength of the electromagnet depends on the number of turns in the coil. As the number of turns increases the number of paper clips ...
