A magnetic field has two two sides, one positive the other negative. Envision a coil of wire located within a magnetic field.The two wire ends from the coil lead out of the field. They can be connected to a complete circuit—say to power a light bulb. When the coil turns, an induced current moves along the wire and through the light bulb, but the voltage is not constant, it is constantly changing as the coil turns.

At point A in the image, the coil is located between the two magnetic fields and the voltage is zero volts.As the coil turns, both sides enter the magnetic field, one into the positive region and the other into the negative region. Voltage begins to rise and the current is flowing in one direction.The voltage rises until it reaches a peak at point B when one side of the coil is centered within the positive side of the magnetic field, and the other side of the coil is centered within the negative side of the magnetic field.build your own air conditioning unitVoltage begins to fall until once again the two sides of the coil are located between the positive and negative sides of the magnetic field at point C.Now the side of the coil that started out entering the positive side of the magnetic field enters the negative side of the magnetic field, while the other side of the coil enters the positive side of the field. central ac parts for sale

Current begins to flow again, but in the opposite direction.Voltage reaches maximum a second time at point D and then begins to fall again until it reaches zero volts at point E.In this fashion, the current alternates directions as the coil turns within the field. Each full turn of the coil provides one full cycle of the current. The current is called AC because it is Alternating Current - that is, it alternates directions.types of hvac maintenanceIn North America's power grid, this cycle repeats 60 times per second (60 hertz). Most of the rest of the world uses a cycle of 50 times per second (50 hertz).The above describes a simplified two-pole, single-phase alternator. In practice, it is more efficient to turn the magnetic field rather than the coil. In modern AC electric generators, the magnetic fields are induced rather than produced by magnets.The addition of a gasoline motor, moving water, steam produced by coal or gas, or some other force to turn the alternator completes an electric generator.

Written Upvoted by Loring Chien, All generators make alternating current, there is no way to get DC from a coil and magnet, they work on the rate of change of the magnetism making a changing voltage in the coil.There are “DC generators”, but they really are not. Internally there is AC, but the AC is sampled at the peaks by some carbon brushes, giving a wobbly simulation of DC.Written Working of an AC Generator is based on the principle of Electromagnetic Induction. According to this principle, A change in flux link to coil induces an electric current in the coil. The direction of the induced current in the coil can be given by Fleming right hand rules. Lenz’s law can also be used to find the direction of current in the coil.You can see more HOW DO AC GENERATOR PRODUCES ELECTRICITY?

In this manner, the emf seen by the external circuit is always the same as the emf generated around the rotatingIn a DC generator, the two ends of the coil are attached to different halves of a single split-ring which co-rotates with the coil. The split-ring is connected the external circuit by means of metal brushes--see Fig. 41.
