Magnetic field of Earth

  1. Jul 22, 2014 #1
    Hi, everyone.

    I read how occurs magnetic field in Earth. However, the temperature of outer and inner core is bigger than Curie temperature of iron. So, I have one question. If they have bigger temperature than Curie temperature, how they can have magnetic properties?

    Thank you.

    They still carry currents. This would be true if the core were made of gold or copper instead of iron.
