Generating Electricity From Earth S Magnetic Field

The field is 5 gauss which means an energy density of 0 001 j m 3.

Generating electricity from earth s magnetic field.

The first and second charged bodies are spaced apart in a direction substantially normal to the earth s surface. A system for generating electricity from the geomagnetic field and rotation of the earth is presented. The earth rotates through the geomagnetic field to form a potential difference between first and second terrestrial charged bodies. On earth flowing of liquid metal in the outer core of the planet generates electric currents.

Generators have pretty powerful magnets in them and if the earth has a similar strength field we d see magnets interacting with it. We are always in the earth s magnetic field which is generated at the earth s core. A point that hasn t been covered is that even with a wire loop rotating through the earth s magnetic field you still wouldn t generate that much electricity. Nicola tesla powered an electric car without the use of a battery drawing power apparently from the earth s electro magnetic field.

A proposed device interacting with this component would extract energy from the earth s rotation to produce electric power. The earth s magnetic field is quite homogeneous over short distances though so the coil would need to move fast and very far to generate much. The rotation of earth on its axis causes these electric currents to form a magnetic field which. Morgan the oil king would have none of it and would not.

The image below shows the range of frequencies for different forms of electromagnetic radiation found in the electromagnetic spectrum. The earth s magnetic field does change a tiny bit but not enough to really generate much. This magnetic field makes compasses work and is also used by pigeons and fish to navigate. Consider for a sense of scale the energy density in the magnetic field near the earth s surface.

Tapping into earth s rotation. Generating power from earth s magnetic field would be ridiculously impractical near the surface. A changing magnetic field does.
