Question

Can you explain how the Earth creates a magnetic field, and what are some of the natural occurrences it influences?

In: Earth Science

Answer 1

You know how when you have a magnet there is a “sphere of influence” close to the magnetic where you can start to feel the magnet’s strength? Magnets can be made from Iron, which is what the Earth’s inner core is mostly made of.

So now imagine a magnet around 1,200 km in size (Earth’s core). The sphere of influence of the magnetic field is “The Earth’s Magnetic Field”
