Detailed explanation-1: -Magnetic fields slow the movement of gas in the convective zone, reducing energy transfer from the core and causing relatively cooler areas called sunspots.
Detailed explanation-2: -Sunspots form and dissipate over periods of days or weeks. They occur when strong magnetic fields emerge through the solar surface and allow the area to cool slightly, from a background value of 6000 ° C down to about 4200 ° C; this area appears as a dark spot in contrast with the very bright photosphere of the sun.
Detailed explanation-3: -Loops of magnetism, or magnetic “ropes, ‘’ are generated within the Sun by flowing ionized gas called plasma. The plasma can flow freely along magnetic field lines. These loops thread through the visible surface (photosphere) of the Sun, and they produce sunspots.
