The Earth's field ranges between approximately 22 and 67 μT (0.22 and 0.67 G). [14] By comparison, a strong refrigerator magnet has a field of about 10,000 μT (100 G). [15] A map of intensity contours is called an isodynamic chart. As the World Magnetic Model shows, the intensity
The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...

The Earth's magnetosphere extends about 10 Earth radii toward the Sun and perhaps similar distances outward on the flanks. The magnetotail is thought to extend as far as 1,000 Earth radii away from the Sun. 1 : Bow shock; 2 : Magnetosheath; 3 : Magnetopause; 4 : Magnetosphere; 5 : Northern tail lobe; 6 : Southern tail lobe; 7 : Plasmasphere
The magnetic field of a magnetic dipole has an inverse cubic dependence in distance, so its order of magnitude at the earth surface can be approximated by multiplying the above result with (R outer core ⁄ R Earth) 3 = (2890 ⁄ 6370) 3 = 0.093 , giving 2.5×10 −5 Tesla, not far from the measured value of 3×10 −5 Tesla at the equator.
The magnetosheath is the region of space between the magnetopause and the bow shock of a planet's magnetosphere.The regularly organized magnetic field generated by the planet becomes weak and irregular in the magnetosheath due to interaction with the incoming solar wind, and is incapable of fully deflecting the highly charged particles.
The Images of Change project provides side-by-side photos of the same place over time to document the environment changes caused by nature and man. NASA's before and after images show Earth's ...
Schematic of the Birkeland or Field-Aligned Currents and the ionospheric current systems they connect to, Pedersen and Hall currents. [1]A Birkeland current (also known as field-aligned current, FAC) is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere.
