What I’m still not getting is how the current itself forms. What can produce enough electrons to power anything by just putting a wire on its opposing fields? Maybe what I’m missing is how to create a battery. I’m assuming the trick isn’t electrons necessarily, but having a material that can have its electron manipulated. So I guess I need to figure out why lithium or whatever can even power anything

We might make an 18min video that took 2 weeks to make, but average view time is just say 4 mins. Our hard work has therefore gone to waste, so we're trying some shorter more concise videos. Then if it's popular, we can go deeper.

This video explains perfectly how an AC Electrical Generator works. But I'm pretty sure there is one misconception. You don't induce a current, but a voltage. The potential different which you now have, leads to a current in the coil. The formula also says it: Voltage = - d(electric flow)/dt, so there is no current with this effect. If I'm wrong, I'm am thankful if you correct me.

@@benmangan9922 It does produce current by changing the difference of the potential on the coil, which is both Faraday and Lenz law (a mix of two) if you move the magnet in and out of the coil you slowly convert the kinetic energy into the electromagnetic field but simply said when you push the magnet into the coil and pull it out nothing noticable happens, because you cant see the electrons you are moving with the magnet itself (Faraday Law), but after several repetitions of the exact same movement you will start to feel the force of the EM field you have created on the coil, counter action of the EM field on the coil which means the field will change potentials to stop you from moving the magnet (Lenz Law), now if you manage to change the potentials on that field, it means you have moved electrons because you cant generate a electromagnetic field without the movement of electrons, when the electrons move they create current and that current creates electromagnetic field.

I'm just learning this stuff too (for fun). But I've been seeing that electricity flow is the flow of an Electric Field. The electrons are required, but don't hardly move. Electrons move very slowly. It is the Electric Field that moves close to c. Still digging on this subject, but this is what I think for now. A multi-step process. 1> Move a Magnet in relation to a "metal conductor". 2> The Magnet pulls and pushes (depending upon N/S pole) on electrons of the valence shell of the metal conductor. 3> The Magnet pulling and pushing on the Electrons creates an Electric Field. 4> The Electric Field flows down the conductor based on a voltage difference between source and sink.

Wow, again an awesome explanation!

Awesome video for non Electrical engineering persons.

Generators create electricity through electromagnetic induction by using a coil of wire (usually called the rotor) that spins inside a magnetic field (often generated by a stationary set of magnets or another coil, called the stator). As the rotor spins, it cuts through the magnetic field lines, creating an electric current in the wire due to electromagnetic induction, as described by Faraday's law of electromagnetic induction. This current is then collected and sent out as electricity through wires connected to the generator.

Wish I had know this channel when I started my study. Great animations and well explained. Thank you ❤️

Please make more video generator maintenance

It is not the distance of the magnetic pole to the coil but the velocity of the pole passing the coil which determines the amount of current beeing produced. The higher the velocity the higher the induced voltage driving the current. If you stop the rotation no current will be generated even if one coil is at the nearest point to the magnets pole as possible. The energy needed to let the current flow comes from the energy to put in to turn the magnet.

Question: When the magnetic field is passing through the copper coil on the positive side for example, making the current flow in a particular direction, what tells it to go THAT particular direction? Do the electrons in the atoms just "enjoy" going left vs right depending on the North or South pole? I assume it has to do with the magnet pushing or pulling in the atoms, but just not sure. Don't want to assume! Thank you for any help on this :)

@DJayAce4

Alright actually I just researched it and will answer my own question, for anyone else down the road reading it and wondering the same thing. So yes, depending on the north or south pole, magnets will either try pulling in or pushing out the electrons in the copper wire.

I like the way you explain things again and again

these 6 minutes were better than 150 minutes of three lessons in my school

An AC electrical generator, also known as an alternator, is a device that converts mechanical energy into electrical energy through the principle of electromagnetic induction. Here's a basic explanation of how electricity is generated in an AC generator: 1. Mechanical Energy Source: To generate electricity, an AC generator requires a mechanical energy source, usually in the form of a prime mover like a steam turbine, water turbine, gas turbine, or an internal combustion engine. This mechanical energy is used to rotate the generator's rotor, which is the central part of the generator that contains the magnetic field. 2. Rotating Magnetic Field: The rotor is made up of a series of magnets, either permanent magnets or electromagnets, which are arranged in a specific pattern. As the rotor rotates, it creates a rotating magnetic field around it. This magnetic field is responsible for inducing an electric current in the generator's stator. 3. Stator and Windings: The stator is the stationary part of the generator that encloses the rotor. It consists of a set of conductive coils, known as windings, which are wrapped around iron laminations. These iron laminations help to guide the magnetic field and minimize energy loss due to heat. 4. Electromagnetic Induction: As the rotating magnetic field from the rotor passes through the windings of the stator, it induces an electric current in the conductive coils. This process is called electromagnetic induction and is based on Faraday's Law of Electromagnetic Induction. The direction of the induced current alternates between the windings, resulting in an alternating current (AC). 5. Voltage and Frequency: The voltage and frequency of the generated AC electricity depend on the rotational speed of the rotor, the number of poles in the magnetic field, and the number of turns in the windings. Typically, the output voltage and frequency can be adjusted using a mechanism called a voltage regulator and a frequency controller. 6. Output and Transmission: The generated AC electricity is collected from the windings through slip rings or brushes, which transfer the electrical energy to an external circuit. From there, the electricity can be transmitted, distributed, and utilized for various purposes, such as powering homes, businesses, and industries. In summary, an AC electrical generator converts mechanical energy into electrical energy through the process of electromagnetic induction, producing an alternating current that can be used for various applications.

Why would the current be stronger (2:12) if we move the magnet faster? The current (amps) is the same, the alternation speed (Hz) is faster/higher, or am I wrong? Update: ohh, never mind. Faster is larger as its the movement of electrons per sec

Though, it'd be nice to know what is best and why. The three-phase seems to work because 120 works, and there are three 120s in the 360 degrees in the "circle". But why not 4 of 90, or 10 of 36, or any other factor of 360?

3:36, I don't understand why when the magnetic field decreases, the electric current does not reverse direction. I agree that when the magnetic field decreases, the electric current intensity will also decrease. However, the direction of the electric current must change because according to Lenz's law: When a magnet approaches, the magnetic induction of the coil will be opposite to the magnetic induction of the magnet, and when the magnet moves away, the magnetic induction of the coil will be in the same direction as the magnet's magnetic induction. The direction of the electric current flowing in the coil is determined based on the direction of the magnetic induction generated by the coil, so the direction of the electric current must be different when the magnet approaches and moves away from the coil, isn't that right? Can you please explain this to me?

@EngineeringMindset

You could, but 3 phases provide a near perfect constant power supply. Adding more phases could improve it further but it will be more expensive to produce the generator so the benefit is outweighed. We would need to use thinner wires also which increases resistance and reduces the amount of current that can be handled. Additionally, the entire electrical network is design and built for 3 phases.
