By moving a conductor through a magnetic field in a way so that it cuts (moves across) the lines of flux of the magnet.

.
Water from a river is diverted and a lake is created by building a large dam.
This water is allowed to fall from the lake behind the dam into the power plant.
This water is directed to several turbines with blades that are pushed by the force of the water (think of a water wheel turned on it's side).
The turbine turns a shaft which is connected to the generator.
The electrical charge created is collected and transformers convert it into useable electricity.
This power is sent out over the power grid. Power lines carry it to all the cities and towns.
Transformers in each town convert the power into different kinds of electricity for different uses: some for factories and some for homes.
Power is there ready for you to use whenever you flip the switch!

Almost all of today's electricity is generated by rotating a coil of wire in a magnetic field. Many different power sources are used to accomplish this.
Other ways of generating electricity are thermopiles (banks of thermocouples wired together), solar cells, and static electricity generators. There are also crystals that convert mechanical vibration into electromatic energy.

Electricity is genetrated with the help of a dynamo. A coil of metal wire is rotated between two magnets; meaning rotating it in magnetic field and then with the help of sliprings and splitrings AC and DC are produced.
