A dynamo passes a magnet past a coil. The movement of the magnet past the wire causes eddy currents to develop which cause electrons to align and move through the wire. If there is enough wire and a strong enough magnet, the current (flow of electrons) is enough to become useful and power a device. It is the growing and shrinking lines of force that cause the electrons to develop this alignment and therefore the electric current.

Can a dynamo be used to generate electricity?
Yes. Because a dynamo converts rotational energy into electricity.
What do you make a dynamo?
Generally it generates a small amount of electricity from rotational movement. Commmon on older push bikes to generate electricity to power lights.
How can you build a dynamo for producing electricity?
A dynamo uses the same physics as an electromotor. Get yourself any electromotor. Spinning it will generate some AC voltage at the power supply contacts.
Who invented dynamo?
Miachael Faraday , who is the father of electricity found dynamo. Dynamo is a device to produce electricity.
How can one use windmills for electricity?
The use of wind power for electricity involves the attachment directly or indirectly of a magnet to the turbine to spin within a dynamo to generate a current.
On the dynamo Where does the energy to generate the electricity come from?
The energy comes from whatever turns the dynamo. This can be any form of mechanical energy, water power, wind, tidal forces, steam turbine, etc.
How does dynamo produce electricity?
Can a dynamo be used without producing electricity??
How dynamo produce electricity?
describe how a dynamo produces electricity? when it moves back and fort it produce electricity The dynamo consists of hollow space which has of 2 magnets, one at the top and other at the bottom. An iron coil is passed through the centre of the dynamo. When this coil rotates, the dynamo produces electricity
Why does the head of the dynamo need to touch the bicycle wheel?
To turn the dynamo in order to make electricity.
Can friction produced by wheels of moving train generate electricity?
yes we can produce electricity by fixing dynamo in traction wheels so heat is produced when the friction of train wheel & track so the dynamo generates an power D.C SUPPLY and is converts into Ac supply so we can use that energy for electric trains use of lights and fans....
What is the dynamo used for?
Electric Dynamo is used in a replacement of permanent magnets. Recently however, electric dynamo is not longer used to generate power in the United States and in Europe.
What energy is produced by a dynamo?
without the aid of other energy sources? no idea... but a dynamo is being run by electromagnetism i think, and thus producing kinetic energy by spinning the shaft... and then the resistance in the conductors, friction in the moving parts, and electromagnetic radiation. just my 2 cents.. >.<
