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 ...

The moving metals in Earth's core create the planet's magnetic field. Our planet sits in a small corner of the Milky Way galaxy, 25,000 light-years from the galaxy's center. Our solar system lives ...

Unlike the geographic North Pole, which marks a fixed location, the magnetic north pole’s position is determined by Earth’s magnetic field ... hopefully one they’d have a slow, centuries ...

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 ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field ... (top of the diagram) swim ...

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 ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...

Now, though, a controversial new paper warns that falling space junk could actually weaken Earth’s magnetic field. If that happens, the author of the paper argues that we could see atmospheric ...
