This is the geo-magnetic field. The geodynamo model for the origin of the earth's field is lent further credence by the fact that the moon which turns around its own axis very slowly once in 28 days has a negligible magnetic field. Also, Jupiter which spins much faster than...

This creates a toroidal, or doughnut-shaped field, as the direction of the field propagates outward from the north pole and enters through the south pole. Earth itself is a giant magnet. The planet gets its magnetic field from circulating electric current within the molten metallic core, ...
Researchers have shed light on how heat is conducted by the inner and outer cores of the Earth to create its protective magnetic field. AsianScientist (Jun. 16, 2016)– Earth’s magnetic field shields us from deadly cosmic radiation. Without it, life as we know it could not exist. But ...
With a pulsar, the light is most certainly polarized because of the high magnetic field. It would also polarize any vacuums that form around it, and with the VLT light was spotted that sported this change (Baker). Other more Earth-based methods are also in development for detecting signs ...
Earth's magnetic field shields us from deadly cosmic radiation, and without it, life as we know it could not exist here. The motion of liquid iron in the planet's outer core, a phenomenon called a "geodynamo," generates the field. But how it was first cr

Lead and gold share the same weight; only an expert can tell the difference. Although it doesn’t share magnetic properties, lead can interact with magnetic fields by moving a powerful magnet past a leaded piece. Nickel Nickel is also found in the earth’s core, making it popular. It shar...
