How is electricity created?

Question

In layman's terms please ;o)

Answer 1

Well, electricity is created when ever you created a permanent mortion across a magnetic field...

Answer 2

basically, electricity is generated by a coil (inductor) crossing a magnetic field.

A stationary stator, and a moving rotor. As the rotor is spun (water, steam, wind), a voltage is generated on the stator.

Answer 3

there are 2 kinds of electricity;

1. static

when two surfaces rub together, one will steal electrons (tiny negative bits) from the other, and each one will have a charge. clouds do this, and when the charge is really high the electrons jump to earth so fast that a flash of light and heat are given off. They cut the air so fiercly that it booms! YAY!

ahem...

2. er... not static or something

charged particles, usually electrons, move through a material in one direction,  attracted by something. This is often a battery. The positive end attracts electrons, and the negative end has lots to spare, so they whizz round the circuit to the positive end. Lemons can do this too, which is how you get lemon powered clocks. (and coke, potatoes, lemonade, lots of stuff does this.)

On the topic of making electricity, like for power lines, a wire moving near a magned will make the electrons move down it. This is magnified by having a huge coil of wire spinning in the middle of a magnet (there's a hole there, it's not magic) and the electricity is pushed along the wires by the magnetic field.

This is also how motors work, but the other way round. Electricity is pushed round the coil, and this makes the coil rotate because of the magnets. That's less easy to understand... probably ignore that.

Answer 4

Friction

Answer 5

You need to create an EMF (electromotive force) to make electrons move. A magnet passed through a copper coil for instance, can create an EMF.

Answer 6

A Static charge can be created on material using friction.  It is only electricity when the charge is spent and the electrons move back to equilibrium.

Flowing electricity can be created in a number of ways.

Electrons are induced to flow on a wire when the wire interrupts an magnetic field.  This is how generators work.  By spinning a coil of wires inside a ring of stationary magnets the wires  are continuously slicing through the magnetic field and the electrons flow.

Electrons are induced to flow in certain chemical reactions.  This is how batteries and fuel cells make electricity

Electrons are induced to flow when light hits certain materials.  This is how Photovoltaic cells work.

All of these methods cause electrons to move along a conductor.  That movement is the force that we tap to power electric devices.

Answer 7

Electricity means flow of charges. When charges flow, we call dat Electricity.Any more helps ? Not by friction

Answer 8

electricity is created by moving a wire (conductor) in a magnetic field.

There are a few ways to do this. By far the most common is to burn a fuel to create heat. Use this heat to boil water, and have the rising steam turn a coil of wire round and round in a magnetic field.

Wind turbines cut out the heat generation and just use the the wind to rotate the coil.

Solar cells work in a completely different way - which is much more complicated and I'm not going to attempt to explain in a paragraph but basically converts the energy present in a photon (a unit of light) into electricity.
