Generating Electricity From Magnetic Field

Magnets are different to other objects.

Generating electricity from magnetic field.

It is running purely on the magnet arrangement. 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. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

This is the principle behind the electric generator. 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. The effects of magnetic fields are commonly seen in permanent magnets which pull on magnetic materials such as iron and. You can turn a piece of iron into a magnet.

The earth rotates through the geomagnetic field to form a potential difference between first and second terrestrial charged bodies. A magnetic field is a vector field that describes the magnetic influence on an electric charge of other moving charges or magnetized materials. 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.

The first and second charged bodies are spaced apart in a direction substantially normal to the earth s surface. This creates a force of energy around the magnet called a magnetic field. This would use more energy than it creates at least on the surface of the earth. Thus this law can be applied to generate a magnetic field and run an electric motor.

Coils of wire are mounted around the shaft. You could have a change in the shape of the actual loop of conductor. When the electricity is switched on the electric magnets create powerful magnetic fields. One you can have a change in the magnetic field.

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. 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. Several years back there was an experiment the space tether experiment to drag a conductor through the earth s. Magnetic fields can be used to make electricity.

Moving magnetic fields pull and push electrons. Remember the flux is just your the component of the magnetic field that is perpendicular to the. If its area increases or decreases that will change the flux. Ampere s law roughly states that a changing electric field creates a magnetic field.

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. However over time the magnets can lose their magnetism so they will have to be replaced at some point to continue to generate electricity.
