According to the authors, this process is called magnetic reconnection – it causessolar flares.
A thorough understanding of magnetic reconnection can provide insight into nuclear fusion and helpIt is better to predict solar storms.
Now scientists from NASA's Magnetosphere Mission, orMMS have developed a theory that explains how the most dangerous type of flash occurs - fast reconnection. It also gives an answer as to why this happens at a constant rate. In the new theory, the authors used a common magnetic effect found in consumer devices, such as sensors that monitor a car's anti-lock braking system and know when a mobile phone's flip is closed.
Magnetic reconnection is a process thatoccurs in plasma, it is sometimes called the fourth state of matter. A plasma is formed when a gas receives enough energy to split atoms, leaving a mixture of negatively charged electrons and positively charged ions. This energetic, fluid-like material is extremely sensitive to magnetic fields.
During fast magnetic reconnectionthe charged particles in the plasma—ions and electrons—stop moving as a group. When ions and electrons start to move separately, they cause a Hall effect, creating an unstable energy vacuum in which reconnection occurs. The pressure of the magnetic fields around the energy vacuum causes the vacuum to explode, which quickly releases a huge amount of energy.
The Hall effect is a common magnetica phenomenon that is used in everyday technology, such as sensors that track the speed of wheels and 3D printers, where they measure speed, proximity, location, or electrical currents.
