is the point in the Northern Hemisphere where Earth's magnetic field lines point directly into the planet. The complex motion of the outer core causes the magnetic north pole to shift tens of ...
the angle at which magnetic field lines intersect the Earth. The turtles use these two pieces of information, which vary at every point on the planet's surface, as navigational markers that help ...
This study, published in the journal Astronomy & Astrophysics, reveals that solar jets can create similar disturbances without causing a complete reversal of the magnetic field. NASA's Parker ...
