How Strong is the Earth's Magnetic Field? (with pictures)

Feb 17, 2021 A horseshoe magnet is about twice the strength of a bar magnet, which is much stronger than the Earth's magnetic field. The region where the Earth's magnetic field lines extend into space is called the magnetosphere, and influences the trajectories of the charged solar wind at distances exceeding 10 Earth radii. . Solar wind, ejected from the Sun in all directions at great speeds, collides

NASA Earth's Inconstant Magnetic Field

Earth's magnetic field comes from this ocean of iron, which is an electrically conducting fluid in constant motion. Sitting atop the hot inner core, the liquid outer core seethes and roils like water in a pan on a hot stove. The outer core also has "hurricanes"--whirlpools powered by the Coriolis forces of Earth's rotation.

Earth's Magnetic Field Strength Past 800,000 Years

Sep 25, 2009 The graph shows the strength of Earth's magnetic field over the past 800,000 years. The last reversal of Earth's magnetic field was 780,000 year ago. The direction of the magnetic field has been "normal" (meaning "like it is today") since then. This normal period is called the Brunhes normal chron. Before the Brunhes normal chron, the magnetic
