The equilibrium between magnetic fields and pressure allows the solar blotches to remain stable anywhere from days to months. And all the while, magnetic fields keep twisting and breaking and rearranging themselves. Magnetic fields are strongest when electrons remain unattached, but as more pressure is exerted, it forces them into pairs and weakens the magnetic field. This is known as magnetohydrostatic equilibrium, which describes the properties of a gas or fluid (such as solar plasma) in a magnetic field. Because solar plasma can conduct electricity, it supports the magnetic field it interacts with.
