Question

Does the sun have an iron core? do iron cores produce magnetic fields?

Answer 1

A theory has been proposed that the core of the sun is actually an iron remnant from a supernova. I don't think it's gotten much support, though.

Iron is not necessary for the sun to have a magnetic field. The sun is plasma (ionized gas), and electric currents in the plasma can produce magnetic fields. Even in the Earth's core, it is thought to be electric currents, and not the magnetic properties of iron, that cause the magnetic field. Iron  stops being magnetic above its Curie point, a bit under 800°C.

Answer 2

No, the core of the sun is mostly helium (there may be a small amount of unfused hydrogen mixed in).

There is no iron in the sun.

The sun's magnetic field is generated by the motion of conductive plasma (plasma is super-heated ionized gas).

Magnetic fields such as on Earth are generated by the dynamo effect - the magnetic field is generated within the molten outer core region where heat creates convection motions of conducting materials (iron and other metals), generating electric currents.

Answer 3

It has mostly a hydrogen core.  Liquid iron cores also produce magnetic fields.

Answer 4

No it does not have an iron core.

In the case of the sun, the current is generated by ionised hydrogen and helium, so as the sun spins there is a current ==> magnetic field.

In the earth it is due to iron

In Jupiter it is due to metallic hydrogen..

You just need a spinning current...
