3. INTRODUCTION
In the present scenario power becomes the major need for human life. Energy crisis is
due to two reasons, firstly the population of the world has been increased rapidly and
secondly standard of living of human beings has increased. Now a days, availability
of regular conventional fossil fuels will be the main sources for power generation, but
there is a fear that they will get exhausted eventually by the next few decades.
Therefore, we have to investigate some approximate, alternative new sources for the
power generation, which is not depleted by the very few years.
By conventional energy sources all the living organisms of all kinds as on the land, in
aqua and in air are affected..Therefore, we have to investigate other types of
renewable sources, which produce electricity without using any commercial fossil
fuels, which is not producing any harmful products. There are already existing such
systems using renewable energy such as solar, winded…for power generation. This
paper proposes a novel technology to convert the rotational free energy available
from rotating machines to electrical energy using repulsion magnet technique.
Due to the scarcity of power generation, much modern technique must be employed
for power production. This project deals with the theory of magnetic repulsion
4. •COMPONENTS
PERMANENT MAGNETS: A permanent magnet (ferromagnet) is a material
that produces a magnetic field. In fact, this is used in every electromechanical
device in the world. A permanent magnet is an object made from a material that is
magnetized and creates its own persistent magnetic field. Materials that can be
magnetized, which are strongly attracted to a magnet, are called ferromagnetic.
Although ferromagnetic materials are the only ones attracted to a magnet strongly
enough to be commonly considered magnetic, all other substances respond weakly
to a magnetic field.
ALTERNATOR:An alternator is an electrical generator that converts mechanical
energy to electrical energy in the form of alternating current. A conductor moving
relative to a magnetic field develops an electromotive force (EMF) in it (Faraday's
Law). This EMF reverses its polarity when it moves under magnetic poles of
opposite polarity. Typically, a rotating magnet, called the rotor turns within a
stationary set of conductors wound in coils on an iron core, called the stator. The
field cuts across the conductors, generating an induced EMF (electromotive force),
as the mechanical input causes the rotor to turn.
5. POWER AMPLIFIER:A power amplifier is an electronic amplifier designed to
increase the magnitude of power of a given input signal. The power of the input signal is
increased to a level high enough to drive loads of output devices like speakers, etc..
TRANSFORMER:A transformer is a static electrical device that transfers electrical
energy between two or more circuits. A varying current in one coil of the transformer
produces a varying magnetic flux, which, in turn, induces a varying electromotive
force across a second coil wound around the same core. Electrical energy can be
transferred between the two coils, without a metallic connection between the two circuits.
According to Faraday's law of induction the induced voltage effect in any coil due to
changing magnetic flux encircled by the coil.
Transformers are used for increasing or decreasing the alternating voltages in
electric power applications, and for coupling the stages of signal processing circuits.
MAGNETIC FRAME:A magnetic frame works based on the repulsive force, when
the main magnet is kepted near the magnets which are connected to magnetic frame starts
repulsing then the magnetic frame starts rotating.
FAN BLADE: When the shaft rotates the fan blades connected to shaft starts rotating.

7. CONSTRUCTION
A magnetic frame is connected to the shaft of the alternator and this
magnetic frame is placed in between the two magnets of same poles.
The alternator is connected to the step up transformer , this transformer is
connected to the power amplifier , the power from this power amplifier is
given to the electrical load.
On the other side, fan blades are connected to the shaft of the same
alternator, by this we can use it as a cooler , this fan blades are mounted on
the stand.
This stand is used to pull in and pull out of the blade set to the shaft of the
alternator .
A tub is placed to circulate the water to the grass around the stand by using
pipe, by this method there is no need of centrifugal pump.

9. WORKING PRINCIPLE
When the magnetic frame starts rotating with the help of repulsive force which is
generated by the permanent magnets, small amount of rotational energy (i.e.,
mechanical energy) that generated mechanical energy is converted into electrical
energy. That conversion takes place through the alternator. The same polarity of
magnets which present in the magnetic disc is rotates due to magnetic repulsion. The
repulsion between the two magnets makes the rotation continuously in the magnetic
disc which is coupled cooler’s magnetic frame through the shaft. Alternator produces
electrical energy. Then the output voltage is increased by the transformer and to
increase the output power we use the power amplifier. The energy is used to drive any
AC loads.
When the shaft of the alternator starts rotating the fan blade connected to same
shaft starts rotating, when the water from the tub is pumped to grass, the grass gets
wet by that the cool air comes out.
To stop the rotation of whole system we are using one iron pulley which is
inserted into the center of fan blades.
10. CONCLUSION
In this presentation we have discussed the theory of magnetic repulsion. The system
uses permanent magnets to produce repulsion and this repulsive force produces a
torque which drives a Alternator to produce electrical energy. It is a nonconventional
type of producing the energy. The existing source of energy such as coal, oil etc may
not be adequate to meet the ever increasing energy demands. Since the model has
only few modifications and more advantages. Future scope of this work is to
implement in industry to generated electricity by the rotational free energy available
from rotating machines to electrical energy using repulsion magnet technique. The
significant conclusions that may be drawn based on the present work may be
summarized as follows:
Model study is done and it is found to give a satisfactory results.
The mechanism proposed is much simpler and continuously produces the electrical
power.
The produced electrical energy is renewable energy which is pollution free.
