What is the source of the sun's magnetic field since the sun is made of helium and hydrogen and is well beyond the Curie point for magnetic materials?

Answer 1

Quite simple really. First, you have to know this: materials within the Sun are so hot that they exist in the heightened state of plasma, where electrons are hardly bound to they positively charged nucleus. The speed at which the Sun rotates causes the plasma to become highly magnetized. This speed also causes the invisible lines of magnetism to become chaotic and twisted. Likewise, the magnetized plasma is the cause of solar flares, prominences, and the highly magnetized solar winds.

Answer 2

The sun's magnetic field originates from its outer layers, particularly the convective zone where the movement of charged particles generates electric currents and, in turn, a magnetic field through a process known as the solar dynamo. This magnetic field is not reliant on traditional magnetic materials and is instead a result of the sun's plasma properties and complex interactions within its interior.
