Question

According to the current understanding of Earth's magnetic field and how magnetic fields are generated, which two components in Earth's internal structure are required in order to generate a magnetic field?

Answer 1

Answer:

a conducting liquid and a rapidly rotating core.

Explanation:

The Earth's magnetic field is generated by the motion of iron and nickel in a liquid state inside the outer core and due to the rapid rotation of the inner core. When a conductive fluid travels through an existing magnetic field, induced electrical currents appear, creating another magnetic field.

Answer 2

Answer:

conducting liquid interior and a rapidly rotating core

Explanation:

A mechanism by which a celestial body such as Earth or a star generates a magnetic field is referred to as DYNAMO THEORY.

Developed by Walter Elsasser, a physcist, he described the process which involves the maintenance of magnetic field over a long period through a rotating, convecting, and electrically conducting fluid.

Hence, according to dynamo theory, a planetary magnetic field needs both a CINDUCTING LIQUID INTERIOR and a RAPIDLY ROTATING CORE so, as to generate a magnetic field.

Earth's powerful magnetic field is made through the relationship of the rapidly rotating inner core and conducting liquid, outer core.
