Answer:
The magnetic field is generated by electric currents due to the motion of convection currents of molten iron in the Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.

ion refers to a substance that has at least one positive and one negative
electrical charge at different locations and the net charge of the entire
molecule is zero. Examples of zwitterions are amino acids.
