Current Sheets

Current sheets are thin regions in space where electrical currents flow intensely in a narrow area. They occur naturally in plasmas, such as the Sun's atmosphere or Earth's magnetosphere, where magnetic field lines break and reconnect. These sheets can release stored magnetic energy suddenly, causing phenomena like solar flares or geomagnetic storms. Think of them as electrical "fault lines" in space's magnetic environment, playing a key role in the dynamic behavior of space weather and plasma processes.
