Faraday Law

Faraday Law

Faraday's law of induction is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF)—a phenomenon called electromagnetic induction. It is the fundamental operating principle of transformers, inductors, and many types of electrical motors,generators and solenoids.[1][2]

electromagnetic induction was discovered independently by Michael Faraday in 1831 and Joseph Henry in 1832.[4] Faraday was the first to publish the results of his experiments.[5][6] In Faraday's first experimental demonstration of electromagnetic induction (August 29, 1831[7]), he wrapped two wires around opposite sides of an iron ring (torus) (an arrangement similar to a modern toroidal transformer). Based on his assessment of recently discovered properties of electromagnets, he expected that when current started to flow in one wire, a sort of wave would travel through the ring and cause some electrical effect on the opposite side. He plugged one wire into a galvanometer, and watched it as he connected the other wire to a battery. Indeed, he saw a transient current (which he called a "wave of electricity") when he connected the wire to the battery, and another when he disconnected it.[8] This induction was due to the change in magnetic flux that occurred when the battery was connected and disconnected.[3] Within two months, Faraday had found several other manifestations of electromagnetic induction. For example, he saw transient currents when he quickly slid a bar magnet in and out of a coil of wires, and he generated a steady (DC) current by rotating a copper disk near the bar magnet with a sliding electrical lead ("Faraday's disk").[9]


Generator

Understanding Electrical Generator is a machine that converts the energy of motion (mechanical) into electrical energy (eclectic).

Working Principle / How it Works Electrical Generator
The generator works by Faraday, ie when a conductor is played in a magnetic field so that the cutting line, the lines of magnetic force at the end of the conductor will incur an emf (electric lines of force) which has units of volts.

Type of generator:
1. The type of generator is based on the location of the poles is divided into:
a. generator pole in: in pole generator has a magnetic field that lies in the rotating parts (rotor).
b. pole generator outside: outer pole generator has a magnetic field that is located on the stationary part (stator)

2. The type of generator is based on a round field is divided into:
a. synchronous generator
b. asynchronous generators

3. The type of generator is based on the type of flow that is raised
a. generator of direct current (DC)
b. generator alternating current (AC)

4. Type generator seen from the phase
a. single phase generator
b. three-phase generator

5. type of generator is based on the form of the rotor:
a. generator rotor salient pole is used at low rpm generator with such as hydropower and diesel
b. generator rotor poles flat (cylindrical) used in the power plant / generator with a round of such high rpm power plant and power plant
