Space magnetic field
WebWhen the solar wind plasma leaves the Sun's corona, it carries with it some of that yellow star's magnetic field. This extension of the Sun's magnetic field into space greatly influences the manner in which the solar wind interacts with planets and, eventually, the interstellar medium. As it travels through space, the solar wind reaches speeds ... Web8. apr 2024 · The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space. This magnetic field is known as the geodynamo. Multiple lines of evidence have shown that the Earth’s magnetic field existed at least 3.5 billion years ago.

Web6. apr 2024 · "The magnetic field is actually a superposition of fields from many current sources," geophysicist Terry Sabaka from NASA's Goddard Space Flight Centre said back in 2024. "The observed SAA can be also interpreted as a consequence of weakening dominance of the dipole field in the region," said fellow NASA Goddard geophysicist … The interplanetary magnetic field at the Earth's orbit varies with waves and other disturbances in the solar wind, known as " space weather ." The field is a vector, with components in the radial and azimuthal directions as well as a component perpendicular to the ecliptic. Zobraziť viac The interplanetary magnetic field (IMF), now more commonly referred to as the heliospheric magnetic field (HMF), is the component of the solar magnetic field that is dragged out from the solar corona by the solar wind flow … Zobraziť viac The plasma in the interplanetary medium is also responsible for the strength of the Sun's magnetic field at the orbit of the Earth being over 100 times greater than originally anticipated. If space were a vacuum, then the Sun's magnetic dipole field — about 10 Zobraziť viac The coronal and solar wind plasmas are highly electrically conductive, meaning the magnetic field lines and the plasma flows are effectively "frozen" together and the magnetic field cannot diffuse through the plasma on time scales of interest.
