Graphical representation of Earth’s magnetic field on Google Earth. The data dates back to 1590 and you can use the time animations to watch how the magnetic field changes over time. Three overlays are included:

  • Magnetic field direction
  • Compass Needles
  • Declination

The time animations require a lot of data to process and might take a while to load all the images.

  • Hello gelib,

    I am sending a news release regarding Earth’s magnetic field that you can use on your blog. Please consider using it. You can find images on my website.

    Earth’s Magnetic Field Is Produced By An External Dynamo System, Not An Internal Dynamo.

    Researcher finds that Earth’s magnetic field is not produced by an internal dynamo. Nor is it produced by ocean current. The dynamo is outside the Planet! New findings by independent researcher, Dennis Brooks, show that Earth’s magnetic field and the planet itself are components of a complex dynamo system, which surrounds the planet. The planet and its magnetic field are part of the dynamo.

    According to this new theory, no internal dynamo or ocean current helps in producing or maintaining the magnetic field because other planets with magnetic fields do not have ocean currents or iron cores.

    Each planet does not have a unique way of producing its magnetic field. The magnetic field of each planet is produced by a planetary dynamo system and its ring current.

    For many years researchers thought that a similar dynamo system was within the planet and that this internal dynamo generated the magnetic field. However, we know now that it is too hot inside the planet to produce and maintain a magnetic field there.

    The planetary dynamo system is composed of a magnetosphere, the planet, the magnetic field, radiation belts, ring current, and charged particles from the solar wind. The planet is the central component of the system and its rotation plays an important part in operating the dynamo and generating ring current. The magnetic field is generated by the system’s ring current, which is made up of charged particles. The magnetic field captures even more charged particles and brings them into the dynamo system as fuel. Everything works together.

    Earth’s inner and outer core simply cannot provide the fuel a dynamo system needs. If earth’s dynamo had to depend on energy from the planet for fuel, the entire planet would have been completely consumed many years ago.

    Scientific discoveries strongly suggest that the Earth’s core ‘magnetic reversal’ (Pole Shift), which is in progress right now, has significantly been a driving force behind Climate Change!

    What the hell should I do when I want to see it in Google Earth?

    I understand that temp over 862 degrees C there in no permanent magnetic fields. Venus is right at 900C and has no magnetic field and slow rotation. Compairing Earth and Venus I believe that if venus was cooled
    to about 270 degrees C it would form a strong magnetic field that would strongly aline it to the Suns magnetic field and it would increase it spine and change its orbit angle. Like a induction mono poler engine
    and should run at about a 24 hour day.
