Question

Explain the connection between Earth's magnetic field and iron.

Answer 1

The Earth's magnetic field is caused by how the earth's core is made. The earth's core is full of iron, especially in the inner core. That inner core is charged metal that produces electric currents that causes Earth's magnetic field. So because the core has iron, we have a magnetic field.

Answer 2

The Earth's magnetic field is somewhat caused by the composition of the earth's core which is rich in iron minerals. There is a solid inner core that is made of iron which makes up to 2/3 of the moon's size. The charged metal of the iron produces electric currents, consequently resulting to Earth's magnetic field.
