What are the differences between a DC motor and DC generator?
the one and only the main difference b/n them is a dc motor takes the electrical energy as its input and gives mechanical energy as its output where as in the dc generator takes the mechanical energy as input and gives electrical energy as its out put In both the case we can't get 100% efficiency because total input can't be converted into output.
What does a generator consist off?
A mixture of minerals and other materials
What Three types of windings are used on dc generator armature?
The winding of this type of transformer are made up of concentric coils. These coils are round, some being very small and other being larger, some have an open hole in the centre, making them shaped like a flattened donut, and some are solid. A few of the manufacturers have migrated into designing their concentric coils into a design which has caused them to be referred to as "spider coils" because the bracing of the coil's structure makes the overall appearance of the coil to resemble a spider's web.
How are the windings of an induction motor made?
The windings of magnet wire are made on a machine that counts the loops of wire as they are formed into usable coils. Once the coils are complete they are installed into the stator slots in a specific order.
In what country are generator parts made?
Many generator parts are made in China and Taiwan. Mainland China's thriving manufacturing sector has attracted a large segment of the businesses that create these component pieces.
What component is made of loops of wire that rotate in the magnetic field provided by the field poles and field coils?
the rotor coils in an electric motor
What are slots in dc generator?
Slots are teeth shaped portions made on outer periphery of rotor and coils are placed in these slots.
What strengthens a magnetic field made by a current -carrying wire?
The number of coils present in it
How to reduce residual magnetism?
Usually the term "residual magnetism" is used in referring to the weak, leftover magnetic force remaining in field coil poles in generators. These generators can be the automotive type, but can also be any other type of generator in which a Direct Current is used in a series of field windings wrapped around field cores to produce magnetic fields around a rotating armature with the purpose of producing electricity from mechanical motion (the rotating armature). The field winding poles/cores are made of iron, and after the generator has been run a few seconds under load, will retain a weak magnetic field even after the generator has been shut down. This is the "residual magnetism". The majority of older-design generators depend upon this weak, leftover field to restart the voltage produced in the armature, rather than the voltage regulator depending upon a battery to restart the generator field magnetism. Residual magnetism gets weaker over time; the time depends in part on the quality of the field pole piece and and how strong the current applied to the field coils was at the time the generator was stopped. To temporarily restore the residual magnetic field, current will need to be applied to the field circuit BRIEFLY; completely disconnecting the generator will be required. Connecting a 6 volt "lantern battery" in the proper polarity across the field winding circuits for a few seconds will establish a residual magnetic field in each field coil/windingzperiodz Proper polarity is critical: backwards polarity will create backwards residual magnetic fields, and the generator will produce backwards-polarity electricity when the armature is spun.
Can electricity be made?
Sure. Add a few choice metals to some chemicals and you have an electric battery. Spin coils of wire in a magnetic field and you get electricity.

Can an electric motor act like an electric generator?
An electric generator is a device that converts mechanical energy to electrical energy. On the contrary electric motors convert electrical energy into mechanical energy. Electric motors and generators have many similarities, generator forces electrons in the winding to flow through the external circuit. The source for generating mechanical energy can be a reciprocating or turbine, an internal combustion engine, a wind turbine or a motor that is capable of generating electricity using some energy source like diesel or kerosene. Many types of electric motors can be run as generators, and vice versa. For example a starter/generator for a gas turbine or Traction motors used on vehicles often performs both tasks.

How does a real generator works?
In its most basic sense a when ever you pass a copper wire through a magnetic field you induce a current of electricity into the wire. This is what a generator does....it creates a magnetic field and turns a coil (called a rotor) inside of it. The current so induced is lead outside by wire and made to do usefull work.
What is a chromosome made up of when it coils?
Chromatin
The purpose of a stator?
The stator is the stationary part of an electric generator or electric motor. The non-stationary part on an electric motor is the rotor. Depending on the configuration of a spinning electromotive device the stator may act as the field magnet, interacting with the armature to create motion, or it may act as the armature, receiving its influence from moving field coils on the rotor. The first DC generators (known as dynamos) and DC motors put the field coils on the stator, and the power generation or motive reaction coils on the rotor. This was necessary because a continuously moving power switch known as the commutator is needed to keep the field correctly aligned across the spinning rotor. The commutator must become larger and more robust as the current increases. The stator of these devices may be either a permanent magnet or an electromagnet. Where the stator is an electromagnet, the coil which energizes it is known as the field coil or field winding. An AC alternator is able to produce power across multiple high-current power generation coils connected in parallel, eliminating the need for the commutator. Placing the field coils on the rotor allows for an inexpensive slip ring mechanism to transfer high-voltage, low current power to the rotating field coil. It consists of a steel frame enclosing a hollow cylindrical core (made up of laminations of silicon steel). The laminations are to reduce hysteresis and eddy current losses.
