The dynamo theory is a scientific concept that explains how celestial bodies, like Earth or certain stars, generate their magnetic fields. According to this theory, a dynamo effect occurs when a conductive fluid, such as molten iron in the Earth's outer core, moves in a way that generates electric currents. These electric currents then produce magnetic fields, which can interact and reinforce each other.
