ELECTRIC + MAGNETIC = ELECTROMAGNETIC *PART 2

Hello guys,

Lets continue with the previous EM Part 1 posted. As we already understand a very simple basic of electricity energy and current path, now it will lead us to magnetic part. As a conductor(previously green path) carrying a current flow through it will produce a magnetic field around it. A moving charge or electron will induce a magnetic field around it and vice versa.

So that how magnetic field induced, as long as we have electron moving, there will be magnetic field induced around it path. So what can be used with magnetic field? Even kids know that magnet have abilities creating a push-pull forces depend on the poles orientation. We have north-south pole for magnet, ask you little-brother to solve it for you.

We are using this forces to create torque for electrical motor. To talk about how we can design an electric motor really take a lot of effort as we need to think and design carefully(base on my own experience building homemade dc motor) to manipulate this forces. Here a link for my friend dc motor project.

If you want more detail, you can read about Lorentz force. This part required a basic vector analysis and lots of equation. I will not go deep about this, it is a waste if we will not cover the basic very well. This article only for simple knowledge sharing. Enjoy Part 3 in progress.

ELECTRIC + MAGNETIC = ELECTROMAGNETIC *PART 1

Assalamualaikum.

Hi everybody, since I've got a request from a friend, so I would like to share with you a basic understanding of electric and magnetic. Hope with the simple example,people who are not involve in electric engineering will also understand how everything works. I'll try my best to make you understand it in the way of story rather than plain note or theory.All the diagram I draw here are free to shared.

Electric energy, I don't want to give the same defination like what you can find in wikipedia, This is what it look like from my understanding: CLICK TO ENLARGE IMAGE

That is the most basic part, I will try not to include any equation as the equation will mess out every simple thing. If you take an AAA batery, connect the +ve and -ve pole with a wire, you will get the diagram of green path above. The electron will flow from -ve pole to the positive while the current are opposite of that. For a long time of connection, the battery will become hot as it continuous release the electron through the wire as short-circuit loop.

At the end of the battery life, the potential of the battery usually 1.5V become only less than 0.5V. At this point,we said that the potential is going to be a ground level 0V or equalibrium pressure for spray can.Example above show the actual electricity application.Red arrow is the direction of current flow( +ve holes transition). Electron are moving through a thin filament which heated up and the energy of it are emitted as visible light photon. This is how light bulb operating. I don't want to put it more detail, as any question we can discussed it in comment below. If you found anything wrong inside this article, let me know as I can change it to be better and reliable. Thank you.
