How the differential rotation of the sun causes sunspots

[Nex]

Hey, um i am really new to this, so i hope i am doing this right... If I am wrong i am sorry...

Homework Statement

Ok, so its probably really easy and I am just being dumb but i am trying to explain why the differential rotation casues sunspots

Homework Equations

The Attempt at a Solution

I have read a bit and i have sort of figured out that its because the sun rotates faster at the poles then at the equator and something about the magnatised matter of the sun making closed loops and slowing the convection currents and thus the heat transfer thus making those areas darker? The whole what the differential roation does to the magnatic matter of the sun confuses me, I have read the information I am having trouble picturing it in my head, which is why i am here, hoping someone can explain it in a way that makes sense.

Again sorry if this is wrong or something :S

The differential rotation of the Sun is caused by the combination of its internal convection currents and its rotation. As the Sun rotates, the internal convection currents cause different parts of the Sun to rotate at different speeds. The equator rotates faster than the poles because the convection currents in the Sun's outer layers are more effective at transferring heat from the middle of the Sun to the surface at the equator than they are at the poles. This differential rotation causes the magnetic fields to be twisted up, creating closed loops that can trap hot gas and create sunspots. These sunspots appear as dark spots on the surface of the Sun and are cooler than their surroundings.
