    “Generator – normally this term is used to describe an alternator which creates AC power using electromagnetism.
    In the most basic sense a generator/dynamo is one magnet rotating while inside the influence of another magnet’s magnetic field. You cannot see a magnetic field, but it is often illustrated using lines of flux. In the illustration above lines of magnetic flux would follow the lines created by the iron filings.
    The generator/dynamo is made up of stationary magnets (stator) which create a powerful magnetic field, and a rotating magnet (rotor) which distorts and cuts through the magnetic lines of flux of the stator. When the rotor cuts through lines of magnetic flux it makes electricity.
    The generator differs from the dynamo in that it produces AC power. Electrons flow in in both directions in AC power. It wasn’t until the 1890s that engineers had figured out how to design powerful motors, transformers and other devices which could use AC power in a way that could compete with DC power.
    While the alternator uses commutators, the generator uses a slip ring with brushes to tap the power off of the rotor. Attached to the slip ring are graphite or carbon “brushes” which are spring loaded to push the brush onto the ring. This keeps power consistently flowing. Brushes get worn down over time and need to be replaced.
    Since the time of Gramme in the 1860s it was figured out that the best way to build a dynamo/generator was to arrange magnetic coils around a wide circle, with a wide spinning armature
    Due to Faraday’s Law of Induction if you take a wire and move it back and forth in a magnetic field, the field pushes on electrons in the metal. Copper has 27 electrons, the last two in the orbit are easily pushed on to the next atom. This movement of electrons is electrical flow.
    The magnets are usually not made of natural magnetite or a permanent magnet (unless it is a small generator), but they are copper or aluminum wire coiled around an iron core. Each coil must be energized with some power to make it into a magnet. This coil around iron is called a solenoid. Solenoids are used instead of natural magnetite because the solenoid is MUCH more powerful. A small solenoid can create a very strong magnetic field.
    Dynamo is an older term used to describe a generator that makes direct current power. DC power sends electrons in only one direction. The problem with a simple generator is that when the rotor rotates it eventually turns completely around, reversing the current. Early inventors didn’t know what to do with this alternating current, alternating current is more complex to control and design motors and lights for. Early inventors had to figure a way to only capture the positive energy of the generator, so they invented a commutator. The commutator is a switch that allows current to only flow in one direction.”
