Please give concise answer

Answer 1

ment. origin of Eadth's magnetic field! There are Many ions are present in earth's envison Due to the Rotation of earth, these Charge carriess ions also jotate with earth sotation. It make a current Carrying" Loops asaund the Earth A current Carrylmy Loop produce magnetic Moni 2R IR The current is different at different places of earth do to variable Linear velocity (e) of icon charge code So it have it's vestical and Horizontul Components of Earth is magnetism at different places on the magnetic Plano" Direction of Earth Horizontal Component along Current sauth - North Groomaticas tomb Plane Br. magnetic Plane Carrying
