Hi All,
I´m quite new to physics (from a biology background) and am hoping someone can give me a quick explanation of what causes the Earth to have a magnetic field. I have read about the dynamo theory but am finding it difficult to visualise or is it as simple as moving currents make an electric field?
Thanks for your help
