Still dont get why first the the E and H field are 90 degrees out of phase but suddenly they are in phase 😢

1:04 - it should be noted that this visual representation is not a sign wave form but momentary pulses as it does not fade in and out. Indeed, radiating from one point wouldn't have the dynamic of traveling along a radiating element, so that doesn't mean it is necessarily incorrect, just not representative.

1:43 While electrons do move it is not the electrons themselves that are moving this distance but rather their electrical field, similar you could say to how a wave travels across water though the actual specific molecules of water aren't traveling the full length of the wave's propagation.

2:30 can we actually imagine it as squeezing electrons? Aren't they in similar distances all the time?

I am not as impressed by this film as most other viewers seem to be. There are two major shortcomings: First, the question of why the "pulsating" electric and magnetic near-fields around the dipole travel out into space is not addressed. Instead, at 5:10 they weirdly move the "field of view" away from the antenna and just claim that there is indeed propagation with E always being perpendicular to H (which, of course, is true, but for somebody without prior understanding of electrodynamics, is not evident why that should be at all) Second, when they "explain" reflection at surfaces, they simply state that the E-vector is instantaneously reversed, while the H-vector is not (8:06). For someone who is not an expert (and therefore the target audience of this movie) this seems completely arbitrary, and no explanation is given as to why. So yes, the film is good in parts, but unsatisfactory in others...

In this diagram animation BOTH the VOLTAGE and CURRENT (fields) are drawn as strongest in the middle of the antenna. As far as I know one of them should be stronger at the tips of the antenna and the other weak at the tips but strong at the feed points.
@TheDesertRat31 3 күн бұрын
I think it depends on the wavelength relation of the antenna and where the feed point is. I recently saw a video that illustrated your exact point, but I'm trying to remember what was said. I found it by accident. I feel like it had to do with an end fed antenna, made at a fractional wavelength and showing why a center fed dipole is so desirable, but an end fed (while more practical in building and mounting) is a compromise electromagnetically. I think it was regarding building a 160m antenna. The guy was explaining the trade offs and difficulties in building such a long antenna for that band.

That illustration is misleading at 5:00, the E field and H field are in phase, there’s no capacitance here right it is an ideal conductor
@dcamron46 8 ай бұрын
He says the peak happen in phase but the description at 5:00 implies they’re not…it’s as if the E and H aren’t maximized at same time in that illustration- which is wrong

Why is the magnetic field coming out from the antenna not even at any point? As far as I know electricity flows evenly in the wire,so why would the center have stronger field than the edges?

If it’s clear then why they do show current and voltage both weak at the tips of the antenna? One of these is strong at the tips, don’t you think?

I was thinking of this applied to people. Do thoughts have a dipole? Female being negative and male being positive? If people are in a circle and meditate together i bet that this would be a powerful energy. I was just looking at a few field diagrams and wondering what they were meaning.

On second thought .. female can be positive n males can be negative... We already took a hit for that apple incident like way back when. Lol
