1. ### B Exploring the Electric Field of a Moving Charge

Are those electric/magnetic field combinations orthogonal? I think it depends on how someone look or think about them. https://en.wikipedia.org/wiki/Classical_electromagnetism_and_special_relativity#/media/File:Lorentz_boost_electric_charge.svg
2. ### B Exploring the Electric Field of a Moving Charge

As decorations to show the varieties of forms of electric/magnetic fields.
3. ### B Exploring the Electric Field of a Moving Charge

Here, "Yes, but it is not useful, and it attenuates rapidly to make EM waves propagating as orthogonal E and M fields." Ok?
4. ### B Exploring the Electric Field of a Moving Charge

So, how do you arrive at the conclusion?
5. ### B Exploring the Electric Field of a Moving Charge

The article in which you said "Yes, but it is not useful, and it attenuates rapidly to make EM waves propagating as orthogonal E and M fields."
6. ### B Exploring the Electric Field of a Moving Charge

I guessed you've read the article, may I ask what is the title of the article? I forgot the title.
7. ### B Exploring the Electric Field of a Moving Charge

Therefore, the electric field for that current carrying wire will be like this. Is there a way to make the electric fields and magnetic fields to be non-perpendicular, for example parallel? Looks like someone can make how the electric and magnetic fields propagate depending on how someone...
8. ### B Exploring the Electric Field of a Moving Charge

So, for this wire in this particular video, the electric fields coming out from this wire excluding the other wires will look like the picture in your link?
9. ### B Exploring the Electric Field of a Moving Charge

In a single wire excluding second and other wires, the electric field will look like this? https://en.wikipedia.org/wiki/Electric_charge#/media/File:VFPt_plus_thumb.svg https://en.wikipedia.org/wiki/Electric_charge#/media/File:VFPt_minus_thumb.svg
10. ### B Exploring the Electric Field of a Moving Charge

Can you think of any links that show the closest representations of what electric fields of every charges, not just individually but instead as the whole, actually look like?
11. ### B Exploring the Electric Field of a Moving Charge

For example, in current-carrying wires.
12. ### B Exploring the Electric Field of a Moving Charge

Can you think of any links that show the closest representations of what electric fields of every charges, not just individually but instead as the whole, actually look like?

Like this?
14. ### B Exploring the Electric Field of a Moving Charge

I don't know how to programmed it myself as I'm just a person who are interested in physics with very limited mathematics background. I tried to find pictures online on how an electric field of a moving charge inside a wire looks like, but there are just too many and I'm confused. What is the...
15. ### B Exploring the Electric Field of a Moving Charge

How does an electric field of a moving charge, for example a moving electron, inside a wire looks like? Does it looks like this with distorted circular radial lines?
16. ### B Seeing both B field lines and E field lines at the same time

I thought the resulting field lines will look like this... The black line is the electric field lines that is also the same electric field lines that we saw in the video. Sorry for the terrible drawing of electric field lines.
17. ### B Seeing both B field lines and E field lines at the same time

What I mean is what will the field lines (including the electric field lines that we saw earlier in the video) look like if we use two erect bar magnets as the conductors instead of the nails like in the video? Did they (both the electric field lines and magnetic field lines) look like this...
18. ### B Seeing both B field lines and E field lines at the same time

So the directions of both E and B/H field lines are exactly the same? Is that what you're saying? Thank you.
19. ### B Seeing both B field lines and E field lines at the same time

So, magnetic field can somehow influence the electric field lines and vice versa?
20. ### B Seeing both B field lines and E field lines at the same time

I don't have the right app for me right now to try to draw what you're describing, but are you saying the resulting line will be similar to what I said which is "field lines that consisted of intersecting and non-intersecting field lines"?
21. ### B Seeing both B field lines and E field lines at the same time

That bolded statement, do you mean if we combined a 2d picture of magnetic field lines and 2d picture of electric field lines we'll never see the perpendicular E and M fields at the same time? What's the context here?
22. ### B Seeing both B field lines and E field lines at the same time

Lets start by standing the bar magnets up vertically instead of laying them horizontally in the container. I think it will look something like this... if the poles that pointing to each other are similar. and this... if the poles are dissimilar. Combine these magnetic field lines with a...
23. ### B Seeing both B field lines and E field lines at the same time

What's the result if we run a current through the bar magnets? Are the results different? What will the magnetic field lines look like?
24. ### B Seeing both B field lines and E field lines at the same time

The materials that person used in the video are a clear plastic container, a 9V battery, alligator clips, two nails as the conductors, a voltmeter, two graph papers with one of them is used to draw the electric field lines and some water. First he put a graph paper underneath the plastic...
25. ### B Seeing both B field lines and E field lines at the same time

Therefore, the result if we use bar magnets as the conductors instead of nails will be like : Is that it?
26. ### B Seeing both B field lines and E field lines at the same time

So, the person in this clip Electric Field Lines Lab (click on the highlighted link on the left to watch the clip) was charging the nails rather than running a current through them? What's the result if we run a current through the bar magnets? Are the results different? What will the field...
27. ### B Seeing both B field lines and E field lines at the same time

I wonder what that will looks like if it is 3D. Do you have any clue? So, in two-dimensional image, the electric field and magnetic field did run parallel if we make two bar magnets as the conductors in an electric field? So, the resulting field lines will be a combination of electric field and...
28. ### B Seeing both B field lines and E field lines at the same time

After watching this clip Electric Field Lines Lab I wonder if it is possible to see both electric field lines and magnetic field lines at the same time by swapping the two nails in the video with two bar magnets, as the conductors as we understand bar magnets are metals and metals are good...
29. ### B Interpreting light as Maxwell's EM wave

The axis is imaginary, correct? We can put the axis anywhere whether on top of the field, below, etc. I have my own opinions regarding the electric and magnetic fields but this is not the "right" place to say anything about it because this entire forum is almost like a cult. Sorry for the...
30. ### B Interpreting light as Maxwell's EM wave

What about unpolarized electromagnetic field? Because next to every magnetic fields are literally electric fields? The perpendicularity of E and M fields only applied to linearly polarized EM field if I'm not mistaken, but natural EM fields are unpolarized.
31. ### B Interpreting light as Maxwell's EM wave

But the electric field and magnetic field for each point in space doesn’t have to be necessarily perpendicular, correct? For example, like in this picture the electric field and magnetic field is not perpendicular http://physics.thick.jp/Experimental_Physics/Section1/figures/fig1-4-2_en.png
32. ### B Interpreting light as Maxwell's EM wave

Because the electric fields are distributed randomly in unpolarized electromagnetic fields, between every magnetic fields will be electric fields too. I hope I can see more pictures of unpolarized EM fields.
33. ### B Interpreting light as Maxwell's EM wave

@Dale @vanhees71 regarding unpolarized electromagnetic field, are the electric and magnetic fields still can be distinguished from each other? Are there pictures that show the orientations or angles of electric fields and magnetic fields if the electromagnetic field is unpolarized? Thank you.
34. ### B Interpreting light as Maxwell's EM wave

Now I got it. First I was a bit confused about what is near field. Thank you. Nevermind, even myself are not sure what the context is.

36. ### B Interpreting light as Maxwell's EM wave

So, we are still not sure? Sorry, I'm confused. The only context I can find is here https://www.embibe.com/exams/motion-in-combined-electric-and-magnetic-fields/ and I'm not sure if this is the right context.
37. ### B Interpreting light as Maxwell's EM wave

Is this an example of a parallel electromagnetic wave? https://qph.cf2.quoracdn.net/main-qimg-d5afa8922da2e560dda3342b9c2cbda3-pjlq
38. ### B Interpreting light as Maxwell's EM wave

Any thoughts on this https://www.researchgate.net/figure/Measuring-parallel-electric-and-magnetic-fieldsMeasurements-l780-nm-of-parallel_fig1_51591625?
39. ### B Interpreting light as Maxwell's EM wave

I wonder if there are actually instances or if there are possibilities for the electric fields and magnetic fields to be parallel (or non-perpendicular) to each other instead of being perpendicular. What happens if the electric fields and magnetic fields are parallel (or non-perpendicular) to...
40. ### B Interpreting light as Maxwell's EM wave

Thank you so much for these responses. Much appreciated. :smile:
41. ### B Interpreting light as Maxwell's EM wave

Can we actually distinguish an electric field from a magnetic field in reality? Without these red and blue colour-coding and if we include every electric and magnetic fields instead of only two such as the vertical waves and horizontal waves, this is what I thought usual light and laser will...
42. ### B Interpreting light as Maxwell's EM wave

I'm sorry for this terrible drawing below, I'm trying to draw a laser beam because it seems to be a fitting example for something like "a single point in space over time or a line through space at a single point in time" as laser beam is a concentrated type of light. Not sure if the drawing is...
43. ### B Interpreting light as Maxwell's EM wave

The first picture shouldn't be taken literally when it comes to imagining what EM waves look like in reality. Correct?
44. ### B Interpreting light as Maxwell's EM wave

Thank you, Dale. Anyway, is this software good? Have anyone tried it https://www-fourier.ujf-grenoble.fr/~parisse/giac.html
45. ### B Interpreting light as Maxwell's EM wave

So the result from the calculations using those math software systems will give us what EM waves look like? I just want to see the closest representation of EM rays if we can somehow look at them like when we are looking at apples, houses, etc. I'm really bad at mathematics :smile: Or, is it...
46. ### B Interpreting light as Maxwell's EM wave

Sorry, but how to do that?
47. ### B Interpreting light as Maxwell's EM wave

Is it appropriate to use this http://www.falstad.com/wavebox/? Thoughts?
48. ### B Interpreting light as Maxwell's EM wave

Sometimes I cannot imagine light as the popular Maxwell's blue and red electric and magnetic wave https://simply.science/images/content/physics/Electromagnetism/em_waves/emv.jpg but I found the image below to be the more accurate representation of how light actually looks like as waves...
