It's your basic electromagnetic device. Pressing the pickup wheel of the dynamo against a bicycle wheel in motion cause the inner parts of the dynamo to spin. What's spinning is a pair of magnets surrounded by coils. When the magnetic field through a coil changes you get electricity. That electricity can then power a light.

What is the purpose of using a bicycle dynamo?
To provide electricity for the bike lights without having to rely on batteries.
What is the function of a dynamo in back wheel of cycle?
It'd be rare to have a dynamo actually IN the rear wheel, far more common to have it at the side of it, driven by pushing against the tire. The purpose of a dynamo is to provide power to bicycle lights. A bicycle dynamo functions just like any other dynamo of the same principle - expose a coil of electric wire to a changing magnetic field and you get a current out of it.
Is the dynamo of a bicycle light ac or DC?
There are two types of electrical generator. One is a dynamo, which produces d.c. The other is an alternator, which produces a.c.
Why does the head of the dynamo need to touch the bicycle wheel?
To turn the dynamo in order to make electricity.
Will there be a difference in electricity produced by a normal bicycle and geared bicycle with the dynamo?
The output from the dynamo varies with the speed of the bicycle. And as a geared bicycle is likely(but don't have to) travel a bit faster than the single speed, it may produce a bit more electricity.
Can you power a motor directly form a dynamo?
Yes, like the dynamo on a bicycle that provides power for the light, instead it can run an electric motor with the help of a few cheap diodes(Bridge diode setup)
What produces the electrical energy in a bicycle?
Either a battery or a dynamo.
Which part of a power station is like a dynamo in your bicycle?
The generator
What happens to the light of a bicycle when you pedal downhill?
Well, assuming that:the light is powered by a dynamo that is driven by the wheelthat pedalling downhill means that you're going faster than usualthen the light will become brighter, because a dynamo(=generator) gives off more power the faster it spins.
Can a bicycle dynamo turn on a radio?
A bike dynamo may power a small radio, but you'd have to turn it on manually first.
How does a dynamo works in a bicycle?
i know how but i'am having a problem of explaining
Where can you find generator lights for bicycles in stores?
Go to a bicycle shop, or the bicycle accessories aisle on a big department store and ask a clerk for bicycle dynamo.
