Which interior layer of the Earth is responsible for Earth's magnetic field?

it say what "interior" layer and then dismisses the solid core which is crucial to the magnetism

This answer is incorrect. The outer core influences the magnetic field, but there would be no magnetic field without the solid metallic inner core.

the graph showed i was correct, but it counted it as wrong. is this going to be corrected soon??

Our planet is awesome
