Generating Electricity From Magnetic Field

Thus this law can be applied to generate a magnetic field and run an electric motor.

Generating electricity from 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 properties of magnets are used to make electricity. When the electricity is switched on the electric magnets create powerful magnetic fields.

It is running purely on the magnet arrangement. The power from the proposed device would be measured in nanowatts but might in principle be scaled up. It could be a change in its magnitude and or it s orientation. This is the principle behind the electric generator.

Remember the flux is just your the component of the magnetic field that is perpendicular to the. You can turn a piece of iron into a magnet. Coils of wire are mounted around the shaft. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

Several years back there was an experiment the space tether experiment to drag a conductor through the earth s. A magnetic field is a vector field that describes the magnetic influence on an electric charge of other moving charges or magnetized materials. As the shaft with the magnets rotates the coils of wire are exposed to changing magnetic fields and an electric current is generated in the wires. However over time the magnets can lose their magnetism so they will have to be replaced at some point to continue to generate electricity.

They show theoretically that a device sitting passively on the earth s surface can generate an electric current through its interaction with the earth s magnetic field. The effects of magnetic fields are commonly seen in permanent magnets which pull on magnetic materials such as iron and. This creates a force of energy around the magnet called a magnetic field. Moving magnetic fields pull and push electrons.

One you can have a change in the magnetic field. Magnetic fields can be used to make electricity. You could have a change in the shape of the actual loop of conductor. Faraday s law may be stated roughly as a changing magnetic field creates an electric field.

This would use more energy than it creates at least on the surface of the earth. In magnets the electrons in atoms at one end all spin in one direction and those in atoms at the other end all spin the opposite way. The earth rotates through the geomagnetic field to form a potential difference between first and second terrestrial charged bodies. Ampere s law roughly states that a changing electric field creates a magnetic field.

The magnetic energy that is used to run a motor over time does not require an outside energy source to generate electricity like the sun or water. Metals such as copper and aluminum have electrons that are loosely held.
