My son wants to know how electricity is made, I'm stumped!?
Answers:
You pass some magnets over a coil of copper wire and as the excited electrons move about they create it.. like magic
tell him that
he won't buy it but hey. depends how old he is
electrons are stripped from atoms and go in a stream down a wire or through the air.
http://en.wikipedia.org/wiki/electricity.
It is made by creating magnetic differences. These differences have to balance out, which creates energy. You can catch this energy and then it is called electricity.
It works the same way with lightning, but that's a bit hard to catch :)
From charged electrons. Read more here: http://en.wikipedia.org/wiki/electricity.

EMF. Electromotive Force.
The simplest explanation is the right-hand rule. Any movement of a conducting wire occuring perpendicular to a magnetic field will generate a current in the third plane. Have a look on Wikipedia for it.
Tell him that when magnets are spun with wires around them, it makes electricity flow from one end of the wire to the other. Tell him that the same force that makes magnets stick to metal is the force that pushes electricity through the wire. That's as basic as I can describe it.
Good luck, he sounds like a bright kid if he's asking questions like that.
Most electricity is made by magnets rotating in a coil of wire or a coil of wire rotating around magnets. This is the way power is generated from nuclear, wind, hydro, and fossil fuel generating plants. All of these use a turbine to turn the generator.
There are other less popular ways of producing electricity such as solar(popular on calculators) and fuel cells.
electricity is the movement of an electron stream through a conduit like a copper wire. electricity can be created any number of ways. the most common is with turbines that use some force like water or heat to make the turbines spin. inside there are two metal gears that work with each other to cause a spark. that spark is a release of electrons that is then sent into the conduit and out to your house.
electricity is formed in many ways eg thunderstorms forming lightening, friction causing static electricity etc. Humans mostly make electricity using generators which are basically electric motors in reverse
When the little hamster runs round the little wheel it makes a a charge this is collected and there you have electricity!
it is made by the motion and bombardment of electrons.
electricity can be generated in many ways
for example from water it can be generated in dams
from a nuclear power plant
from wind mills, from solar panel
Tell him moving objects create heat and heat is energy so when heat is passed down a wire the energy can be used at the other end . It should satisfy his curiosity but it won't get him into university ?
Back to basics. Electricity is "made" using something called induction. Basically you get a coil of copper wire, many coils and on the end of those coils you put a light bulb, then get a magnet and move it in and out of the coils (in the centre of the coil) this produces and inductive charge in the coils and should (if there are enough coils and the magnet is strong enough) light the bulb (use the lowest wattage you can find, A torch bulb). That is the basics of how electricity is "made". Of course you will get all sorts of technical answers about electrons and neutrons and potential differences (voltage to you and me), but the basics still remain the same, coils and magnets, only in the large generators the magnet is just spun inside the coil and high speeds to produce more power but the basics are the same.
matter is made up of tiny particles called atoms.these are made up of charged particles :electrons{negatively charged} and protons{positively charged}.since the amount of electrons and protons in an atom are equal the atom is neutral.but electrons can be removed from the atoms by processes like friction and chemical reaction.when these electrons are allowed to flow across a conductor it forms an electric current.thus electricity is the flow of electrons past a conductor.thus electricity is made by flowing electrons past a conductor(eg electrons flow from a battery across a wire forming electricity){there are other means also but in every case youn have to flow electrons across a conductor}
