Generating Electricity From Earth S Magnetic Field

A system for generating electricity from the geomagnetic field and rotation of the earth is presented.

Generating electricity from earth s magnetic field.

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. Generators have pretty powerful magnets in them and if the earth has a similar strength field we d see magnets interacting with it. 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.

The rotation of earth on its axis causes these electric currents to form a magnetic field which. The field is 5 gauss which means an energy density of 0 001 j m 3. 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. The image below shows the range of frequencies for different forms of electromagnetic radiation found in the electromagnetic spectrum.

We are always in the earth s magnetic field which is generated at the earth s core. The earth rotates through the geomagnetic field to form a potential difference between first and second terrestrial charged bodies. The other option is to move the inductor in the magnetic field. The earth s magnetic field does change a tiny bit but not enough to really generate much.

Tapping into earth s rotation. Consider for a sense of scale the energy density in the magnetic field near the earth s surface. A changing magnetic field does. On earth flowing of liquid metal in the outer core of the planet generates electric currents.

Generating power from earth s magnetic field would be ridiculously impractical near the surface. This magnetic field makes compasses work and is also used by pigeons and fish to navigate. 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.
