This deflection convinced him that magnetic fields radiate from all sides of a wire carrying an electric current, just as light and heat do, and that it confirmed a direct relationship between electricity and magnetism. At the time of discovery, Orsted did not suggest any satisfactory explanation of the phenomenon, nor did he try to represent the phenomenon in a mathematical framework. Soon thereafter he published his findings, proving that an electric current produces a magnetic field as it flows through a wire. It had far-reaching consequences, one of which was the understanding of the nature oflight.
The magnetic field responsible for lining up all those little bits of metal into a proper Mohawk haircut is due to the movement of electrons. Similarly, if you allow electrons to move through a metal wire, a magnetic field will form around the wire. A generator is simply a device that moves a magnet near a wire to create a steady flow of electrons.
The action that forces this movement varies greatly, ranging from hand cranks and steam engines to nuclear fission, but the principle remains the same. One simple way to think about a generator is to imagine it acting like a pump pushing water through a pipe.
Only instead of pushing water, a generator uses a magnet to push electrons along. This is a slight oversimplification, but it paints a helpful picture of the properties at work in a generator.
A water pump moves a certain number of water molecules and applies a certain amount of pressure to them.
In the same way, the magnet in a generator pushes a certain number of electrons along and applies a certain amount of "pressure" to the electrons.
The "pressure" pushing the electrons along is called the voltage and is measured in volts. For instance, a generator spinning at 1, rotations per minute might produce 1 amp at 6 volts.
The 1 amp is the number of electrons moving 1 amp physically means that 6. Generators form the heart of a modern power station. Patron Saint of Electricity Nineteenth-century British physicist and chemist Michael Faraday paved the way for our modern electricity-driven world.
The famed inventor created the first electric generator, called the dynamo, as well as the first electric motor.One simple way to think about a generator is to imagine it acting like a pump pushing water through a pipe. Only instead of pushing water, a generator uses a magnet to push electrons along.
This is a slight oversimplification, but it paints a helpful picture of the properties at work in a generator. In Lesson 1, the concept of electric potential difference was discussed. Electric potential is the amount of electric potential energy per unit of charge that would be possessed by a charged object if placed within an electric field at a given location.
The concept of potential is . Increase voltage across wire by the variac and connect ammeter and voltmeter to measure current and voltage. Set the variac scale to adjust voltage and current value of nichrom wire and current is passed through periodically .
Benjamin Franklin and Electricity Electricity was on people's minds in the s, but not in the way we think about it today. People used electricity for magic tricks by creating sparks and shocks.
This essay will explore the development of currently accepted ideas on the nature of electricity, magnetism.
The paper will start in the Ancient Greeks and will continue to the present. In the process of developing our modern understanding of electricity, magnetism and electromagnetism, our predecessors carried out investigations which have now become accepted and replicated in modern classrooms.
History of Electricity - The oldest civilization known to understand electricity was the ancient Greeks because of the electric fish in the Nile River.
