Question

Why does the magnetic field of the sun always change?​

Answer 1

$\huge\colorbox{violet}{❥︎Answer}$The sun's writhing magnetic fields – caused by the movement of the charged material, known as plasma, it's made of – leads to constant change on timescales from milliseconds to billions of years. We see giant solar eruptions such as solar flares and coronal mass ejections that can last minutes to hours approximately every 11 years. It happens at the peak of each solar cycle as the sun's inner magnetic dynamo re-organizes itself.
