• Introduction
In day to day life there is lot of load shedding take place waste of electricity in disco, dancing bar, clubs, etc. We require electricity in our day today life so taking under consideration. We make this project. Project name is Electricity Generation from dancing floor.
We make this project taking under consideration of future expansion here we use Faraday Law in that he explained the attraction and repulsion of electromagnetic induction. We use two plywood for this project. Upper plywood consist of permanent magnet and base plate consist of electromagnetic coil
When we dance on floor the attraction and repulsion take place in coil and magnet the magnetic field is cut by magnet and coil and electricity is generated.
This project we can install in school, collages, speed breakers, skywalk, etc. from that we can save electricity in future and there will be no loads shedding in future
Working
When we walk or dance on upper plate due to weight upper unit press down side and electrical energy generated due to change in magnetic field near coil and upper plate at its original place due to springElectrical energy generated by coil connect to led due to this they are glow and that energy connect to battery for changing the connection of battery connect to ‘EMERGENCY LIGHT CIRCUIT ” by which 18 watt CFL tube light glow
By using faraday law of electromagnetic the ground side plate and also LED’S are placed on ground side plate and on that plywood sheet of is placed when we walk or dance on that plate then due to vibration electrical energy created in which LED’S glow.
BATTERY :-
A Battery is a source of electrical energy0 these are the devices, which maintain current by transferring chemical energy into electrical energy. This electrical current is maintained by an electro motive force (e.m.f.) inside the battery. The e.m.f. in the battery is equal to the potential difference between its terminals where there is no current flow, because there is no internal voltage drop.
Cathode:-
It is either metallic case as in a Dry dell or a metallic rod as in Leclanche cells though which the current leaves the solution. E.g. Zinc electrode.
COIL AND MAGNET
The coils in the photo above on the left are going to be fixed and placed on top of the magnet in the photo on the right which will rotate.
the magnets are placed with alternating north and south poles facing up which will crate alternation current in the output of the alternator. Sounds great, but I intuitively felt there was a problem. And this is where I had to do some learning about magnets and coils. And what I found out was that when the magnet passes over the coil, as it first approaches the coil the current in the coil begins to flow in one particular direction. As the magnet begins to pass over the coil, half of the coil’s current is trying to move in one direction and in the other half of the coil, current is trying to move in the other direction. Nothing’s going no ware. Now as the magnet exist the coil, current begins to move in the opposite direction of when the magnet approached the coil.
This is how so important magnetic flux is in relation to the magnet. Now to create electrical power we need that wire or coil to cut through those lines of flux. But we also need to understand what happens when it does.
The first thing we need to understand is that depending no. how the magnetic flux is cut will depend on how much power is developed and in what direction current will flow. The way the coils above were cutting the magnetic flux you had current attempting to flow in both directions at once. Not a good design because you don’t get much net power.
what is an electromagnetic coil?
An electromagnetic coil is a device comprising two distinct elements: a conductor and a core. The conductor is most commonly made from solid copper wire, which is wrapped around a solid metal core. each time the wire is looped around the core, it si called a turn. Multiple turns are considered to be a coil.
The most common use of an electromagnetic coil is that of an inductor that stores energy within its magnetic field. Considered a passive electrical component, an inductor has no gain and cannot control the directional flow of the energy. The way an inductor harnesses energy is by the electric current passing through its body.
This reaction is due to Faraday’s law of induction. Which states that “ The induced electromotive force or EMF within a closed circuit is equal to the time rate of change of the magnetic flux through the circuit.” As one of the basic components of electronics, inductors delay and reshape alternating currents. The magnetic energy in an electromagnetic coil is measured in units of henries, named after Joseph Henry, an American inventor.
In order to function within a circuit, electromagnetic coils need to have terminals connected to the wire. These terminals are called taps. Taps are generally either coated in varnish or wrapped in a form of insulation tape. This helps keep the electricity from escaping the electromagnetic coil and also secures them in place. The electromagnetic coil with taps at either end is called a winding.
When two electromagnetic coils are placed together, it is called a transformer. This provides the ability to transfer energy between two electrical circuits through magnetic coupling. Essentially, electricity can be transferred from circuit to circuit without the use of moving parts. When a third electromagnetic coil is placed in proximity to the transformer, energy can be further transferred. This third coil is called a tickler coil
An induction coil is a type of electrical transformer that uses a low voltage DC supply to produce high-voltage pulses. The coil is made up of two coils made up of insulating copper wire wound around a common iron core. The first coil is small, usually made up of tens or hundreds of turns of coarse wire. This is known as the primary winding. The second coil, known as the secondary winding, is made up of thousands of turns of fine wire.
CONCLUSION
At the time of making of this project many problem are created by guidance of teacher and respected person many problem are solve after making this project show to teacher and people they all are happy and congrates us as well as bless us
Make survey of market this tyoe of unit not available in the market if this type of system launch in the market then it is easily available and without advertising the company give more profit in few years the use of this system it is possible to reduce time of load sheding
