Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. [4] One stripping mechanism is for gas to be caught in bubbles of the magnetic field, which are ripped off by solar winds. [5]

The three plot lines show the total field strength (blue), radial (vertical) field component (magenta) and the horizontal (south to north) field component (yellow). Field strengths are given in microteslas and the geographic latitude is given in degrees. The field strength reaches up to around 60 microteslas at the poles.
The magnetic field partially shields the Earth from harmful charged particles emanating from the Sun. The field is stretched back away from Sun by solar particles and radiation pressure. The geomagnetic field is generated (and regenerated) as the conducting fluid of the Earth's mantle and core, driven by convection of heat from deeper in the ...
Magnetic declination map at sea-level for the year 2010 derived from WMM2010. The World Magnetic Model ( WMM ) is a large spatial-scale representation of the Earth's magnetic field. It was developed jointly by the US National Geophysical Data Center and the British Geological Survey .

The magnetic field of larger magnets can be obtained by modeling them as a collection of a large number of small magnets called dipoles each having their own m. The magnetic field produced by the magnet then is the net magnetic field of these dipoles; any net force on the magnet is a result of adding up the forces on the individual dipoles.
“The rumbling of Earth’s magnetic field is accompanied by a representation of a geomagnetic storm that resulted from a solar flare on November 3rd, 2011, and indeed it sounds pretty scary."
