Generating Electricity From Earth S Magnetic Field

This magnetic field makes compasses work and is also used by pigeons and fish to navigate.

Generating electricity from earth s magnetic field.

Morgan the oil king would have none of it and would not. The first and second charged bodies are spaced apart in a direction substantially normal to the earth s surface. A proposed device interacting with this component would extract energy from the earth s rotation to produce electric power. Nicola tesla powered an electric car without the use of a battery drawing power apparently from the earth s electro magnetic field.

Tapping into earth s rotation. 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. The earth s magnetic field does change a tiny bit but not enough to really generate much.

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. Although the earth s magnetic field is not aligned exactly with the planet s rotation axis there is a component of the field that is symmetric about this axis. Consider for a sense of scale the energy density in the magnetic field near the earth s surface. The image below shows the range of frequencies for different forms of electromagnetic radiation found in the electromagnetic spectrum.

Earth s magnetic field also known as the geomagnetic field is the magnetic field that extends from the earth s interior out into space where it interacts with the solar wind a stream of charged particles emanating from the sun the magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the earth s outer core. Generating power from earth s magnetic field would be ridiculously impractical near the surface. 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. A system for generating electricity from the geomagnetic field and rotation of the earth is presented.

The other option is to move the inductor in the magnetic field. We are always in the earth s magnetic field which is generated at the earth s core. Generators have pretty powerful magnets in them and if the earth has a similar strength field we d see magnets interacting with it.
