When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right ... and generators to operate. In the Earth (see image below right), the ...

Such is the case with the Earth's magnetic field. Every so often, our planet's magnetic poles reverse polarity (see When Compasses Point South). Compass needles have always pointed north ...

This dynamic movement generates Earth's magnetic field, a protective shield against harmful solar radiation and cosmic ...

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

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.

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 nano particles and materials. Scientists at Flinders ...

From there, the other directions can be figured out. Without the Earth’s magnetic field, this useful phenomenon would not occur. Whilst the geographical and magnetic north poles aren’t always ...

Their analysis showed the complex magnetic field can determine increases in module fill factor and falls in maximum power. Researchers at the Multimedia University of Kenya have claimed the Earth ...
