Earth’s Magnetic Field: A New Theory

About one week ago I received a comment from a reader in which he has tole me that Earth’s magnetic field is not produced by an internal dynamo. He has certainly given a lot of time in his theory and believe me that is very interesting too. Well I’m presenting some fraction of his theory here…

New Theory: Earth’s magnetic field is not produced by an internal dynamo. The magnetic field and the planet are parts of a complex dynamo system surrounding the planet. The system includes the planet, the magnetic field, radiation belts, and ring current. The same is true of the other planets. Saturn, Jupiter, Neptune, and Uranus are visible components of otherwise invisible planetary dynamo systems, which are all housed within a magnetosphere. According to this new theory, there is no internal dynamo within the planet. Planet Earth does not have a unique way of producing its magnetic field. Nor do the other planets. Each magnetic field of each planet is produced in exactly the same way, by its planetary dynamo system.


A planetary dynamo system is composed of a complex network of components including a magnetosphere, a planet, a magnetic field, radiation belts, ring current, and charged particles from the solar wind. The planet is the central component of the system and its movements also play an important part in operating the dynamo and generating current. Planets that rotate fast usually have a stronger magnetic field, and planets that rotate slowly, have weaker magnetic fields.  The dynamo system captures charged particles from the sun and uses them as fuel. The particles are moved into different areas of the system to perform different functions in fueling the dynamo. It’s the planet’s movement that helps to produce the system’s current.


The magnetic field is a component of the dynamo and is generated by the system’s ring current. Ring current is an impressive component of the dynamo system. It is made up entirely of charged particles and provides the energy necessary for producing the magnetic field.  The magnetic field captures the charged particles from the solar wind, and brings them into the dynamo for fuel. All the components and forces work together to make up the planetary dynamo. Some researchers believe that a similar dynamo system exists within the planet and this internal dynamo system generates the current that produces the magnetic field


However, we know now that a magnetic field cannot be produced in earth’s outer core because of the intense heat. All materials lose most of their magnetic properties when raised past a certain temperature called the curie point. The Curie temperature of iron is about 1043 K. This means that the inner and outer core of the planet is too hot to produce and maintain a magnetic field. It’s simply too hot for a magnetic field to be produced and maintained there. Even if a dynamo could exist in such an environment, it would not last very long without a constant supply of quality fuel. Earth’s 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.

    Yes, but what about Mars?

    It spins at about the same rate the Earth does, but it doesn’t have a respectable magnetic field at all?

    Any thoughts?

    Yes dad, I’ve some stuff is here
    you can check it there as well as you can read comment of my reader.

    Hmm..interesting about what happened to Mars’ magnetic field.

    I suppose a huge collision could do it.

    Could I use the premise in my story I’m writing?

      Yeah… Why not? Consider using it as Dennis asked. I certainly haven’t done it yet I’ve published abstract. But I think I should use this in my next posts. I haven’t even read his some of his theory , after thorough study I’ll certainly use it in my upcoming posts.

    Thats Too nice, when it comes in india hope it can make a Rocking place for youngster.. hope that come true.
