“He bathed in the sun’s light, and it burned away his fear, and his hope.” —Parables of the Allspring
Definition/Summary:
Current sheet
- Electric current that is confined to a surface, rather than being spread throughout space
- The largest occurring current sheet in the Solar System is the so-called Heliospheric current sheet, which is about 10,000 km thick, and extends from the Sun and out beyond the orbit of Pluto
Magnetohydrodynamics (MHD)
- The field of science studying these sheets is this is the study of the behavior of electrically conductive fluids: if there is an electric current through part of the volume of such a fluid, magnetic forces tend to expel it from the fluid, compressing the current into thin layers or “sheets” that pass through the volume
