Earth's Changing Magnetic Field

It is not a perfectly symmetrical shroud around the planet but far from it as it fluctuates with the changes in the planet's dynamo (electricity generating) core and strength of the individual magnetic field lines This magnetic cocoon varies in shape and strengths due to fluctuations in the magnetic field generated from the earth's iron core

Q A: heating magnet

As you heat a magnet you supply it with more thermal energy so the individual electron spins (like tiny magnets themselves) become more likely to be in high-energy states Yes iron ceases to be strongly magnetic (i e is not a ferromagnet) when heated to 1043 K called the Curie temperature
