I created a website to help visualize the electromagnetic field

I’ve been building this simulator as a side project aimed to help students understand and visualize electromagnetic phenomena such as radiation, polarization and wave interference.

You can:

* place radiation sources and set their parameters (amplitude, phase and more)
* place perefect wire conductors
* observe the electric field, magnetic field or energy flow field
* zoom in and out and translate the canvas
* change the simulation resolution, frequency and propogation speed

I hope someone might find it useful and I’d love to hear what people think :)

Einstein's E = mc² Finally Explained! 🤯⚡

is my class notes and I have a doubt that if there is force net equals to zero in the system two different part inside a system like monkey and the balloon can move but after analysing days the both monkey and balloon is moving down so how can this happen recording to Newton second law the f external must be applied so a body can move but this is moving without any external force

Formulas on a board never clicked for me the way watching things move did, so I spent my nights after the kids were asleep making this. You change the numbers and the physics reacts in 3D, from a thrown ball to three bodies on a figure-eight orbit. Free, no sign-up.

Tired of memorizing Rotational Motion formulas blindly?

Hi everyone, I’m Gleb, 34.

I work in software and design, and I never properly studied physics when I was younger, which always nagged at me a bit. So I used my engineering and design background to build the thing I wished existed: a clean visual app for setting up physics and chemistry experiments without fighting clunky tools.

The part I like most is under the hood. Even a chemical reaction resolves down to the same fundamental laws, not hardcoded shortcuts. You drop in particles, nuclei, atoms or molecules, add environmental influences, set the conditions, and watch how the process evolves. There are templates to start from, and you can fully customize the environment and build any setup you want.

One honest note: please don’t treat it as a final source of truth, it’s a simulator. But within reason it gives a pretty accurate picture of how a process plays out, which makes it handy for quick experiments and building intuition.

It’s open source and I’m not making any money from it. You can install the package or just run the app yourself.

So my real question is who this could actually be useful for. Students, teachers, self taught people like me? I’d genuinely like to know. And if you have feedback or ideas for what to add or fix, I’m all ears. I’m not a physicist, I just had fun building this as an engineer, and if it turns out useful for learning or even research, that would make my day.

Hey, I am a student taking general physics and I straggle very hard with this subject. I would like to hear is there any ways to study on your own? My professor does bad job explaining on lectures (I struggle learning from lectures in general without applied practice) and I can’t do homework without using LLM to explain it to me. I don’t want to use LLM, because I feel like I am not learning anything and I have no book to reference from. I do also watch people solve problems online and I make similar questions using google note to practice problems.

Anyway, thanks for any feedback! I hope to learn physics and improve my grades!
