Best Answer

It uses a permanent magnet which is rotated by a crank. The spinning magnet is positioned so that its north and south poles passed by a piece of iron wrapped with wire. It was discovered that the spinning magnet produced a pulse of current in the wire each time a pole passed the coil. Furthermore, the north and south poles of the magnet induce currents in opposite directions. By adding a commutator, it is possible to convert the alternating current to direct current.

Yes it can and the otherway aroud a DC motor can be used as a dynamo


Difference between ac dynamo and dc dynamo?

1. AC Dynamo has full rings whereas DC Dynamo has split rings. 2. AC Dynamo produces alternating current whereas DC Dynamo produces direct current. 3. IN AC DYNAMO, CURRENT KEEPS CHANGING EVERY HALF OF A CYCLE WHEREAS IN DC DYNAMO, CURRENT FLOWS IN SAME DIRECTION.


Is dynamo an AC generator?

DC generator

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.


What is a loop or cool of wire that can rotate?

AC and DC Dynamo, galvanometers, etc...


Why cant you generate DC directlyinstead of generating AC and converting it to DC?

Yes, by using a dynamo (which produces d.c.) instead of an alternator.


How do you charge a battery using dynamo?

A "Dynamo" is a DC charger; these will overcharge any battery there is and requires a regulator circuit, they will produce voltage proportional to their rotation. Simply hook it to the battery (watch your positive and negative) and crank the generator / dynamo.


Can a 9 volt motor rotate 9 volt dynamo?

Are you going to use the 9-volt motor as a dynamo, and the 9-volt dynamo as a motor? Yes, the motor can rotate the dynamo because DC motors and DC generators are actually the same thing--they just apply power to the terminals of a motor to make it turn, and turn the shaft of a generator to make power appear at the terminals. Having said that, if you're going to try to connect the shaft of a 9v motor to the shaft of a 9v dynamo, and use the dynamo to power the motor so as to create a perpetual motion machine...that won't work. The motor wastes a little bit of energy, as does the dynamo. It is possible to build a device that uses a motor to drive an alternator, which is the AC version of a dynamo. You power the motor from the AC grid, and power something that's very sensitive to noise on the line from the alternator. This is called a Motor Generator set, and it's how they powered Cray-1 supercomputers.


What kind of electricity does an alternator make DC or AC?

It makes AC ( alternating current ) . That's why it's called an alternator. A DC generator would usually be called a dynamo.


How do you convert DC motor to dynamo?

take two dc motors..................... connect the spindle of 1 motor to a hollow pipe so that the pipe should also rotate when the motor is given dc current (one can take an empty pen refill for that).... now fix the spindle of another motor to the other end of the hollow pipe...... the two terminals of the 2nd motor is now the terminals of the dynamo which will generate dc current........


Can electricity be regenerated by connecting electric motor to a dynamo?

The question is mine......take one dynamo and a motor (both of them are DC).. If The Dynamo is 12v and the motor is 9v...and connect together.....means the rotating shaft of a motor is connecting using a belt then the other end connected to the rotating shaft of the dynamo ......connect the wire parallel......let start... take a cotton thread of 15 cm ...then round the thread on dynamo rotating shaft the pull it....the current from dynamo flows to motor that action make the motor rotates but not constant.....
