Veritasium -- How Special Relativity Makes Magnets Work.

<< < (19/47) > >>

TimFox:
In the relativistic electron accelerators made by my former employer, I assure you that the electrons go faster than 0.707 c.
The timing with respect to the microwave-frequency excitation of the cavities wouldn't work at the frequency and dimensions where they do, in fact, work quite well.

Yes. That is a problem for my theory. And i would be surprised if standard science gets the measurement of the speeds wrong.
If an electron can never attain  c, then an orbiting elektron can't orbit once the atom nears  c.
Hence i say that the atom can never attain say 0.71c, so that the orbital elektron can still orbit with some kind of speed, say c/100. No that’s not a good gedanken, c/100 might demand a limit of 0.99c for the atom. An orbital speed of  nearly c would demand a max atomic speed of 0.71c.
Anyhow, my thinking here arises from the idea that an atom flattens to a 2-dimensional disc if it gets to a speed of c.
I say that if the atom has a speed of c plus the elektrons have a speed of c then that demands a total speed of 1.41c, hence i invoke a lower speed limit for an atom, such that the total speed for the elektron duznt have to reach 1c.

But all of that supposes that the em forces in an atom propagate at c. Praps they propagate at more than c, in the nearfield so to speak. Still thinking.

Need? Could you still make GPS system if there were not relativistic effects? Sure.

But these effects are there, and you need to needs to make allowances for it. This is due to the difference of the passing of time in a semi-synchronous orbit compared to where the receiver is, and for the journey between the two. The calculations needed for approximating the required correction can be found on page 88 of https://www.gps.gov/technical/icwg/IS-GPS-200D.pdf.

This thread give me flashbacks to usenet back in the day, reading Archimedes Plutonium and his Plutonium Atom Totality theory.

CRT duznt need relativity koz the designers don’t need relativity.

I've shown you how it gets used. You can stick your fingers in your ears and go 'lalalala no it doesn't.' And Steinmetz laughs at you.


--- Quote ---Anyhow, i am still waiting for u to explain to me how STR can help B' to make an mmf (ie having already used STR to make an mmf from B). No hurry.

Your entire understanding of the phenomena is shoddy 'krapp' so you wouldn't even understand any such answer (if the foundation of your question wasn't even on already super faulty premises). You can't even read the equations.

Let's not forget how little you admit to knowing,

Translation:
"Herp dee derp, I don't even know the first thing about relativity."

And you want to get all worked up about relativistic transformations of the E-field in current carrying wires - and you don't even know what a high school AP physics student knows about electrons and special relativity.

This material is too advanced for you. Go back to secondary school.  :scared:
