Do you know how a generator generates alternating current?

In short,the generator is a device that moves magnets near a pile of copper wires to generate a stable flow of free electrons. This might help you imagine the generator as a pump that pushes water through pipes.

If you ever moved a paper clip with a magnet when you were a child, you have lifted the lid on a fundamental principle behind the operation of an alternator: the movement of electrons.

Conductive materials (conductors) are composed of atoms with "free electrons".Move the magnet towards the paper clip, and you will force the free electrons in the paperclip to move. That's why you can use the magnet to lift the paperclip. In contrast, the atoms that make up materials such as wood and rubber have no free electrons and are not conductive (insulators), which is why your magnet won't pick up a toothpick. Simply put, a generator is a device that moves magnets near a pile of copper wires to generate a stable stream of free electrons.

This might help you imagine the generator as a pump that pushes water through pipes. It's just that the generator doesn't push water but uses magnets to move free electrons along the copper wire, thereby generating electricity supply. The pump moves a certain number of water molecules and applies a certain pressure to them. Similarly, a generator moves a certain number of electrons and applies a certain pressure to these electrons. In a circuit, the number of electrons driven is called the ampere number or current, and the pressure that drives the electrons is called the voltage. This analogy is a bit too simplistic, but it should help you draw a picture of the properties that work in a generator.

The generator is based on the principle of "electromagnetic induction" discovered by British scientist Michael Faraday in 1831. Faraday found that if an electric conductor like copper wire passes through a magnetic field, current will flow (or be induced) in the conductor. Therefore, the mechanical energy of the moving wire is converted into the electrical energy of the current flowing in the wire.

Generator of two main parts can use mechanical or electrical terms to describe: mechanical: rotor: rotating part of the generator.

Stator: static parts of the generator.

Electrical:

armature: generator power components. The armature winding generates current. In an alternator, the armature is usually located on the stator. Magnetic field, magnetic field component of generator. The magnetic field of a generator can be provided by an electromagnet or a permanent magnet. The excitation coil is usually installed on the rotor of the alternator.
