Electric field lines from oscillating charge
Вставка
- Опубліковано 11 вер 2024
- Simulation of an oscillating charged particle/sphere, which oscillates in vertical direction. Even though the charge moves at relativistic speeds, special relativity is not considered in the simulation.
First a silly close view at the oscillating charge is shown, followed by the same charge seen further away including three wiggly field lines. Finally the same thing with 100 field lines.
Far away from the charge the transverse part of the field lines completely dominate over the longitudinal part, which in turn is more prominent close to the charge. This is a well known feature of EM waves - the fields oscillate perpendicular to the direction of propagation. The magnetic field lines are manifestly not visualised here.
Done in Mathematica 11 and ffmpeg 4.1.
Finally, a nice and well done representation which doesn't rely on steady images from outdated books. This is good content!
Thanks a lot! I'm glad to hear that.
What course is this for?
Is this good for a course in what science branch?

My recommended is just now like 30 second videos of things like this now and im not complaining
lol same
lol based
*Charge at rest - static electric field but no magnetic field observed
*Charge in uniform motion - electric field with magnetic field component is observed
*Accelerating charge - electromagnetic field oscillations are propagated through space
Sweeeet dude, u know all these guys who do phys sims should get together and make an online phys textbook complete with animations and simulations along with the usual textbook explanations, would be super tight
I feel like I've just walked in on a meeting of galaxy brains who actually know what they're talking about and I'm just a first grader lmao
UA-cam recommendations work in mysterious ways.
These are electromagnetic waves!
Just like how if you throw a rock in water, it creates water waves, which is caused by up and down motion of water,
A electric field works in similiar way,
You take a charge, like a proton or electron, and move it up and down, like shown in the video, the electric field also moves up and down creating waves just like water, these waves are called electromagnetic waves.
If you increse the rate at which you ossilate a charge, it increases the frequency of the waves, i.e how much the electromagnetic waves moves up and down in 1 unit time.
The least frequency gives you radio waves, used in radios
You shake it faster, you get microwaves, which are used in micowave ovens!
You shake it even faster, you get infrarred rays, which are used in night goggles.
You shake it even faster, you get the light that we see! starting from red and moving down the rainbow colors to violet!
This gives an impression that the amplitude is increasing.. maybe it's just my perception, I don't know.
I understand your concern. However, the wiggly lines are field lines, only telling the spatial direction of the field in a plane of oscillation of the charge. The amplitude of the field strength is not visible in the video. Such a field strength could be visualized by a density of the field lines, a thickness of the field lines, or the like. The field strength shall drop as 1/r (Coulomb potential). As the EM energy is proportional to the absolute value of the field strength squared, integration of the EM energy on any surface enclosing the oscillating charge gives a constant, in accordance with the energy principle.
@@animations_ag so like water ripple?
@@beaclaster yea thats how waves work
@@knopfir actually waves work because the moon.
@@dreamer097 mf thinks physics will break down if the moon didn’t exist (I know what they meant but it’s still so wrong.)
More details would be appreciated. What does colour represent? What does the wiggling on the sides represents? I understand basic EM but I cannot interpret what this graphic is showing me. Is it a monopole with a fixed charge? What does the field look like in front of the charge at a fixed point? I cannot interpret any useful information from this graphic without knowing what the plot elements represent. Also usually the density of field lines represent field strength, but if that were the case shouldn't the field be anisotropic in intensity?
Single charge/charged ball, etc., oscillating in vertical direction. The color is for visualization only - sorry for that. I think the field lines appear more dense horizontally away from the charge. That would probably be better seen by using more field lines.
Glad I seeing good channels like this one lately.
that charge is just vibeing
I don't have a clue what this means but as an artist this is an invaluable reference!
This is super cool. Would you mind sharing your code?
Of course! It’s an nb file and I don’t have access to Mathematica anymore, so I have no possibilities to clean up the script. If I remenber correctly, the code is an utter mess to say the least. Send me a mail and I’ll send a reply including the file.
@@animations_ag hey I’m not sure if you’ll reply but I’d also really love to see the code!
@@cardinality1975 Send med a mail, and I'll return the script.
@@animations_ag what's your mail?
Let me tell the future: this channel will become famous very soon
This is a very very good demonstration of what polarization looks like
I'd like to see one where it's traveling in a small circle
This makes perfect intuitive sense
Probably one of the best explaination (idk if that's the correct word) ever made
Intriguing. Can you use Green and Purple next time?
So it means that the body of the craft should be made from a diamagnetic material, because the movements of lines of force (the vortex) creates a charge on the body of the craft and when soundwave resonates, it effects the dielectric field so we could amplify or dampen the field.
These plates shall be vibrated in between two magnets of opposite poles
So you're saying the mushrooms weren't lying to me?
Now try seeing how groups of particles behave when you use different "charges", see if it has a relative gravity style effect, maybe even combine your current code with it after to see if it can force some to break free of the gravity field every now and then
_Dewey B Larson's Reciprocal Systems Theory Of Space And Time posits -- and entirely demonstrate -- what is space, time, electricity and magnetism. We live in a universe of motion; the speed of light; scalar magnitudes. There is no zero, there is unit speed, or, light. Time is the reciprocal of space and is three-dimensional. Very important to start with a correct reference system...._
_That's_ Dewey Larson.
Great Video!!!😎👍
What does the color represent? Towards the end, the total envelope of the electric field looks like it's going spherically outwards even when you have an oscillating charge, but the envelope is visible/is an artefact of the coloring, hence my question.
The reason the electric field lines look wiggly is due to the magnetic field, is that correct?
Do electric field lines move when not oscillating in other words what causes the attraction 🧲 from magnets when there is empty space in between them?
Can I reach you here?
I have a question about the 3rd arrangement. Looks similar to my digital art work using hyperspace.
This is how a photon is emitted
What makes the charge oscillate in things that emit an electric field? How is that related to a magnet?
What happens if we use a magnetic material as part of the aircrafts body?
So the reason why magnetic strength drops so fast with distance is because the waves go from a steady outward push to a more perpendicular bilateral push? Am I understanding that correctly?
The reason for the drop in strength is purely a distance effect, since the magnetic field from a current goes as 1/r. However the strength of magnetic field you measure does depend on the polarisation of this field. The polarisation in this setup of the magnetic field is along the azimuthal direction, perpendicular to the oscillations of the electric field lines in the animation.
I love it
now i want to see the path of a 2nd charged particle along those field lines.
Thank you 🙌💕
Yea! thank you fellow human, can you pls simulate induced magnetic field form the changing electric field and show us how these two fields go in phase and produce electromagnetic waves.
Sincerely

It's how rhythms works
Somehow this is really faszinating
Now make it 4D
Oh yeah. It *would* be more extreme when perpendicular to the motion, wouldn’t it?
Basically my reaction. Great example
Imagine if the title was just called "bol", people would think this is just a shitpost.
Do these move at the speed of light?
Yes.
Wow this tickled something in my brain..correlate this to. Quantum Spintor. Maybe.... Give me time...
Brilliant.
Ah yes of course, the circle and the lines and sometimes more lines and they’re red and blue and waving. It all makes sense now.
Based
Can someone explain this in baby terms
Electric charges influence and are influenced by something called an electric field (think of how planets are caught in orbit by a gravitational field and planets themselves make influences on that field, too). If we take a charge and "shake" it like we're doing here, this visualizes the electric field surrounding that charge and shows its propagation through time.
@@brandonklein1 ah thank u
