Explain how the sun’s rotation contributes to its magnetic field.

• The sun’s rotation causes charged particles to move, generating magnetic fields through a dynamo effect.

• The sun’s rotation increases its temperature.

• The sun’s rotation creates sunspots directly.

• The sun’s rotation has no effect on its magnetic field.
