Question

What is the cause of the Earth’s magnetism?​

Answer 1

Answer:

• The Earth's magnetic field is mostly caused by electric currents in the liquid outer core. The Earth's core is hotter than 1043 K, the Curie point temperature above which the orientations of spins within iron become randomized. Such randomization causes the substance to lose its magnetization.....

Answer 2

${\huge {\blue {\underline {\overline {\boxed {\mathcal{ANSWER}}}}}}}$

The cause of the Earth’s magnetism is due to the circulating ions that are highly conducting in the core of the earth.

It results in the formation of the current loops. These current loops are the reason behind the formation of the magnetic field.
