The mission is designed to gather information about the microphysics of magnetic reconnection, energetic particle acceleration, and turbulence — processes that occur in many astrophysical plasmas. [3] As of March 2020, the MMS spacecraft has enough fuel to remain operational until 2040. [4]
Magnetic reconnection is a breakdown of "ideal-magnetohydrodynamics" and so of "Alfvén's theorem" (also called the "frozen-in flux theorem") which applies to large-scale regions of a highly-conducting magnetoplasma, for which the Magnetic Reynolds Number is very large: this makes the convective term in the induction equation dominate in such regions.
Multipotentiality is an educational and psychological term referring to the ability and preference of a person, particularly one of strong intellectual or artistic curiosity, to excel in two or more different fields.
FreeFlyer has been used to support many spacecraft missions, for mission planning analysis, operational analysis, or both. Specific mission examples include the International Space Station (ISS), [7] the JSpOC Mission System, [8] the Earth Observing System, [9] [10] Solar Dynamics Observatory (SDO), [11] and Magnetospheric Multiscale Mission (MMS).
Transcranial magnetic stimulation is similarly argued to have demonstrated that weak EM fields can influence brain activity. [citation needed] McFadden proposes that the digital information from neurons is integrated to form a conscious electromagnetic information (cemi) field in the brain.
The brain's magnetic field, measuring at 10 femto tesla (fT) for cortical activity and 10 3 fT for the human alpha rhythm, is considerably smaller than the ambient magnetic noise in an urban environment, which is on the order of 10 8 fT or 0.1 μT. The essential problem of biomagnetism is, thus, the weakness of the signal relative to the ...
In animals, the mechanism for magnetoreception is still under investigation. Two main hypotheses are currently being discussed: one proposing a quantum compass based on a radical pair mechanism, [2] the other postulating a more conventional iron-based magnetic compass with magnetite particles.
Swarm is a European Space Agency (ESA) mission to study the Earth's magnetic field.High-precision and high-resolution measurements of the strength, direction and variations of the Earth's magnetic field, complemented by precise navigation, accelerometer and electric field measurements, will provide data for modelling the geomagnetic field and its interaction with other physical aspects of the ...
