Explaining the science behind the northern lights, and why 2025 could bring more opportunities to see them. #ExtremeNature ...

a fixed point where the Earth’s axis meets its surface. Instead, magnetic north is the changing location where the planet’s magnetic field lines converge. This field is generated by the ...

Since its launch on March 12, 2015, NASA’s MMS, or Magnetospheric Multiscale, mission has been rewriting our understanding of magnetic reconnection, a key physical process that is important across the ...

The compass needle points in the direction of the Earth's magnetic field ... direction each time join the points to show the field lines The needle of a plotting compass points to the south ...

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 ...

Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

The geographic North Pole, or “true north,” is a fixed point where all lines of longitude converge. In contrast, the magnetic north pole is the northernmost point of Earth’s magnetic field ...
