NASA recently released an illustration of the sun?s magnetic field placed over an image taken by the Solar Dynamics Observatory.
Magnetic dip causes the compass to dip upward or downward depending on the latitude. Illustration of magnetic dip from Norman's book, The Newe Attractive. Magnetic dip, dip angle, or magnetic inclination is the angle made with the horizontal by Earth's magnetic field lines. This angle varies at different points on Earth's surface.
On the topographic maps of the U.S. Geological Survey (USGS), for example, a diagram shows the relationship between magnetic north in the area concerned (with an arrow marked "MN") and true north (a vertical line with a five-pointed star at its top), with a label near the angle between the MN arrow and the vertical line, stating the size of the ...
This image is in the public domain because it contains materials that originally came from the U.S. National Oceanic and Atmospheric Administration, taken or made as part of an employee's official duties.
The sun’s looping magnetic field lines, which form a tangled web of structures more complex than those on Earth, are difficult to study directly. To grasp what’s going on, scientists create ...
New research indicates the sun’s magnetic field originates much closer to the surface than previously thought, a finding that could help predict periods of extreme solar storms like the ones ...

The sun is typically observed when the Sun's center is about one solar diameter above the horizon. [4] [a] Typically the compass will have a stop in the side of the box, which the observer pushes when the Sun is lined up in the sights. This fixes the compass card, from which the magnetic azimuth or amplitude can be read. [3] [b]
