hats off to you sir .... I was searching this video since 2 days and I cant find satisfactory answer . but your this video is mind blowing .... your way of teaching is amazing .... simple and understandable. again thank you soooooo much sir for help. may GOD bless you.
So why is the power supply chattering ? Is that a charge/discharge cycle we're hearing. ? Something like a flyback transformer on an old TV that is arcing where it shouldn't be...?
Question: Does that electron flow also has a magnetic field around it? and if so I'd like to know if we for example put only the north pole of a magnet all the way around the ray will there be parts where the ray will be attracted to the magnet and others where it will be repelled? Thanks!
Exacto, el flujo de electrones también crea un campo magnético a su alrededor, en el primer ejemplo con el tubo TRC , el norte de dicho campo entra a la pantalla (X) y se enfrenta al norte del imán debilitándose la fuerza magnética en la parte superior del rayo, por esa razón, el haz de electrones se inclina hacia arriba (Ley de la Fuerza de Lorentz). En otras palabras, la fuerza del campo magnético es superior en la parte de debajo del rayo, debido a que aumenta el flujo magnético o refuerza el campo magnético principal.
Why is it that the positively charged particles deflect upwards while negatively charged particles deflect downwards, acc. to the right-hand rule, as shown in the video?
Dear Arcan, Our demonstration equipment manager is James Coburn at Utah State University. You could write to him to request information about equipment used and how to assemble it.
@@physicsdemos Hi... I would really love to do the experiment myself... If possible can I get an E-mail of him so I could get in touch and ask for info... It will be of great help... -Love from Philippines
Hello, I would like to know why the electron light shown by your experiment is green and sometimes in other videos is purple? Other questions: Can we make this electron flow move in the shape of an aspiral coil? If so, would this electron flow manifest the same electromagnetic field as a physical coil? With 200KW of energy, could we shoot the electrons farther?
@@physicsdemos And if we make a flow of electrons in motions that are similar to a spiral coil, would a coil-like electromagnetic field be created? We need to create a magnetic field from a coil artificially, this will open many doors for experiments. As our friend below said, the color is produced by the gas present in the tube, in which case your gas used must be the one mentioned by him: "Cuz of zinc sulfide" Greetings from Brazil my friends!!
Does this tube emit X-rays or other high velocity particles that penetrate a human's carcass and sterilize him ? In high school (1978) I found something similar in a science closet. All it needed was power. Went home and asked my Dad about it. He grabbed the phone and started making some demands to the admin folks and professors to get that think away from stupid students. Many years later, we never did have any kids. Related? Don't know. don't care. Best wishes to all that avoided the Clot Shot. -- 5.22.24
Professor, I'm the only one here saying that it's just a big BS? What you say is this: "to UNDERSTAND we use right hand rule where the force for electron comes out upword from my palm. And this is WHY electron behaves like this." Really? Isn't this the most "scientific" way of saying that I don't have any f*cking clue what's going on? What you recite here is just of a way to remember how the particle behaves, not an explanation of what's going on per se. While the video is entertaining nonetheless, I doubt that your "explanation" has any scientific impact on how things really are. This is also true even if you put a formula next to your right hand rule to prove "mathematically" your way of remembering. Good god, I miss times when scientists acted more like a philosophers toward a real understanding, not toward how to skip steps to put it in practice.

One of the best cathode-ray experiments found on youtube
thank you professor that helped
a lot.
Best cathode ray experiment. ...
Thank you very much sir
Thank you for your simple but very good demonstration
You are welcome!
hats off to you sir .... I was searching this video since 2 days and I cant find satisfactory answer . but your this video is mind blowing .... your way of teaching is amazing .... simple and understandable. again thank you soooooo much sir for help. may GOD bless you.
Extremely nice demonstration
Thanku so much for explaining I was trying to figure it out for so long
are u bts army
Namjoon will be proud of you
great simple concise explanation
Thanks!
These videos are the pride of online world
Woah.....that was quite good sir!☺️

Thank you so much, this was really helpful
Why cathode ray is neon green
Thanks for the demo
I am aslo giving the link of this video to my students. thankssssss alot sir
Can you please make a demo of canal rays
0:32 this guy is an x-ray vision robot confirmed.
You are on the right track to enter the competition for the stupidest comment ever.
Why is it that the positively charged particles deflect upwards while negatively charged particles deflect downwards, acc. to the right-hand rule, as shown in the video?
If we connect a ameter it's wire what is the current?
Why it cathode ray is slant
Sir Instead of right hand rule
can we use Fleming left hand rule ?
Sir it would be helpful if we could know the equipments used and how they were assembled.. Thank you!!!!

@@arcangel5598 Yes, just Google "James Coburn Utah State University" to find his e-mail address.
@@physicsdemos Thank you so much!!!
What is the fluorescent screen inside the CRT made of? I've been wondering for a long time.
It is a phosphorescent material, (there is a difference b/w fluorescent and phosphorescent) usually zinc sulphide.
Great explanation sir❤
Thank you so much professor

The green light is created when the electrons hit the screen. The electrons themselves are not colored.
Cuz of zinc sulfide

Greetings from Brazil my friends!!
You have good experiment with good experience
Very good and easy way to learn this
hats off sir
What property of the screen make the electron appear green?
I dunno but ZnS is usually used
Thank you. That helps.
Para cargas negativas es mejor utilizar la mano izquierda y para cargas positivas la mano derecha.
Sir, why we have used right hand rule here,
Since we have to find direction of force the we can't we use left hand rule here?
We can. Just the results will be the opposite.
100x better then teacher explaning it on Whireboard
Very informative
Interesting sir 🙏
oooo my new light saber
Thanks for the clear explanation.
I LOVE YOU THANK YOU
Nice
❤❤❤❤

its a shame he didnt label his experiment with positive/negative ends, and north/south ends of the magnet.
