BASIC CONSTRUCTION OF GENERATOR

Generator
        The voltage induced in the generator is the total number of turns multiplied by the rate of change in magnetic flux in the conducting wire or coil,
E=Ndf/dt
E = induced voltage in generator terminals
N = number of turns .n coil
df/dt = rate of change in magnetic flux with respect to time

     The greater the number of turns constitutes to higher voltage produce and also the increase in the rate of change in magnetic flux also constitutes to higher voltage produce.
        Magnets are the second common object that produces magnetic field aside from Earth. Once you place a metal, wire or any conducting material in the magnet it produces a stationary current. The current can be utilized only if there is a change in magnetic flux, meaning you have to cut the magnetic flux that a conducting material experiences. To cut the magnetic flux it is either you have to move the magnet or you have to move the conducting material. That is also the basic idea on how the generator can produce electricity and power. There are materials that are parctical or best to use as conducting bodies, such as magnetic wire or copper wire. These are the most commonly used magnetic wires in the generator.

Construction Of Simple Generator
        Permanent magnet motor is also a generator. It can either act as a motor at the same time is can also act as a generator. To show some basic application about generator, we will use some common motor to make as a generator. The motor that we will be using is from an old toy car. Other parts are LED(Light Emitting Diode), connecting wires and Multimeter(to measure the peak voltage output).

Pictures will be uploaded next time..
        Once you turn the motor, the LED light will glow indicating that the voltage is being produced. To produce more voltage you must either in the number of turns of the coil or to increase the speed of revolutions per second of the motor. In conclusion, to produce more power, you must use larger motor.
