Question

Where is the moving electric field that causes Earth's magnetic field? A.)earth surface B.)in space C.)earth mantel D.)earth core

Answer 1

Answer:

D) core

Explanation:

The magnetic field is caused by the electric currents that occur in the core. The core is basically a hodgepodge of metals and really hot materials. Some of the metals, including iron and nickel, cycle around in the core in a process called convection. These convection currents lead to the electric currents and from there the magnetic currents.
