When we use Fleming's Left Hand Rule for the direction of deflection of electrons, shouldn't we consider the direction of flow of current (instead of direction of motion of electrons). Fleming's Left Hand Rule states that the middle-finger must point in the direction of flow of current, not motion of electron (or xyz). Considering that, the deflection of electrons would be in the opposite direction as stated. Please consider.
Thank you very much. When I was high school student, I could not understand. I am now 52 years old and I understood the experiment. Thank you very much.
Vah vah... So professional I loved it!!! You didn't slow down and just kept going! And if viewer wants to understand he has to put in the effort vah vah! So refreshing in this age of unacedamy byjus and whatnot!!! Thank you for a beautiful crisp like a pakoda answer!!!
Thank you so much! i finally found a video that adequately shows how Thomson figured out this charge to mass ratio. Hope you have videos on other experiments too
i know im asking the wrong place but does anyone know a tool to log back into an instagram account..? I was stupid forgot the password. I love any assistance you can offer me
@Louie Graham thanks so much for your reply. I found the site through google and I'm waiting for the hacking stuff atm. Seems to take quite some time so I will get back to you later when my account password hopefully is recovered.
According to Flemings left hand rule the force due to Magnetic field must be opposite to what is shown. In Fleming's Left hand Rule Velocity is in Currents direction. As we are dealing with electron beam we must consider the opposite direction of velocity.
why do the electrons act like a monopole (S) at the JJ Thomson experiment ? If you apply a magnet around the tube from the outside without external electric field, the beam ray deflects towards the N-pole and repels the S-pole. From the Stern-Gerlach experiment, an electron has a magnetic dipole moment. So it could have N-pole as well. But it seems that the electrons on the Thomson experiment don't have the N-pole. Why is that ?
If the charge of an electron must relate to the mass of an electron to maintain the mass ratio of an electron, then calculating the mass of an electron using that ratio would depend on the calculation/measurement of the charge of an electron. And if the measurement of the charge of an electron depends on the charge of a proton, then it would not relate to the real mass of an electron. So perhaps, many small electrons are making an opposite charge to balance the charge of a proton.
A moving electron beam has charge, every moving charge has a magnetic field. "All moving charges produce magnetic fields. Moving point charges produce a complicated but well-known magnetic field that depends on the charge, velocity, and acceleration of the particle. It forms closed paths around a line pointing in the direction in which the charge is moving. " I wonder if an electron beam has a magnetic field as if it were running on a conducting wire? Another question, if this fired electron beam moved in the same motion as a spiral solenoid, would the electron beam produce the same magnetic field as a spiral solenoid?
I m thoroughly confused by this video to be very honest .....When u have no magnetic field how can u use the equation v=E/H which was due to cancellation of Electric and magnetic fields but when magnetic field is present no electric field will be cancelled .....How are u using that equation here?
Muhammad Affan e and v are the only unknown variables, considering that the magnetic and electrical force cancel each other the velocity is the same with or without the forces, so the this equation still applies
Ok, good explanation by a theorist for an idealized system, but useless for a real experiment. The capacitor plates obviously can’t extend the whole length of the tube, and this makes the modeling significantly harder. Bottom line, if you’re doing this experiment with equipment, don’t rely on this video.

By convention, the direction of current is considered as opposite to the direction of flow of electron (Class 10th NCERT)
Wow what an explanation....sir how have you made this animation?
How it was explained

@Louie Graham It worked and I now got access to my account again. I'm so happy:D
Thank you so much, you really help me out!
@Clark Zion glad I could help :D

Madhuresh Bhattacharya You're right. Just as I thought.
+Madhuresh Bhattacharya So the polarity of magnets must be reversed .
if u have got any idea abt this plz inform....
One of the best video i have seen... Sir could you please tell me which software did you use to make this video?
Thanks for the great explanation!
This took me some time to understand lol. Didn't think it would be so complex.
Thanks for the tuto!
Kindly check whether Fleming's left hand rule is applied correctly (elections are neg charged and there motion is opp. To conventional current)
You're right.. he hasn't applied that rule appropriately
@D.P The Mass actually it was developed by the late 19th century. .
So fleming probably must have done developing this rule by that time..
..
@D.P The Mass actually .. we don't use fleming's left hand rule for figuring this out..
Recommended video..- magnetic force by bozeman science..
True I was wondering the same thing
well done..gud..presentation..i like it..this gud why to explain
Wow such a helpful video.. Thanks 👍👌👍👌
Thank You. It was of great help.
a really great explanation, thanks a lot for the video
Thank you sir for clearing our concepts.
Thank you for such a good lovely explanation
thanks for sharing such a knowledge
Nice work @SoumitraDas
awesome vedio.........................well explain
using newton's equation... on electrons can be done sir????????
Beautiful explanation 🙏🙏🙏👍👏👏👏
why do the electrons act like a monopole (S) at the JJ Thomson experiment ?
If you apply a magnet around the tube from the outside without external electric field,
the beam ray deflects towards the N-pole and repels the S-pole.
From the Stern-Gerlach experiment, an electron has a magnetic dipole moment. So it could have
N-pole as well. But it seems that the electrons on the Thomson experiment don't have the N-pole.
Why is that ?
You nailed it....I am impressed
Thanks for this beautiful explanation
thanks sir..................... wonderful explanation
Why the ray has deflected in opposite direction when aluminium plates are electricised
Excellent explanation
it helped me a lot thank u sir
Really for me too👍👍
Sir if we change the direction of electric field what is happens??
Value of wavelength is in mm or cm??
Really nice explanation
Thank you very much professor
Very good explanation
wow sir you explained very nicely thank you so much
....😍😍😘
from where do we have to measure x?
Great work....
Wah mza aagya sir thanks a lot
Thanks a lot.............it was great explanation.
Suberb explanation
Thanks... helped a lot☺️

excellent sir!
Mathematical calculation is quite complex.
Any other method to calculate it sir!!!
Nice Explaination with diagram
It is not phosphorent material but is zinc sulphide . Ty
A moving electron beam has charge, every moving charge has a magnetic field.
"All moving charges produce magnetic fields. Moving point charges produce a complicated but well-known magnetic field that depends on the charge, velocity, and acceleration of the particle. It forms closed paths around a line pointing in the direction in which the charge is moving. "
I wonder if an electron beam has a magnetic field as if it were running on a conducting wire?
Another question, if this fired electron beam moved in the same motion as a spiral solenoid, would the electron beam produce the same magnetic field as a spiral solenoid?
Thank you, sir. This video cleared all my doubts on the topic.
thanks
Thank you sir
Thank You so much sir for best explanation 👍🔥💞 mza aa gya sir literally 😁
How deflection of light was happen??
This experiment is in which class
how the beam has a straight line path if there is only force along y axis and not along x axis i mean it should follow curved path
Thanks a lot
Thaankkk you so much and carry on
It contain all that I was looking for
When we attach alluminum plates with battery then one will anode. Then electrons should be attractive this anode maa why it is passing continuous
thank you!!
V well explained😊
thank u sir
thank you
Thanx sir
Good help
The magnets are labelled wrong way around.
Please what's the right way
Thanx a lot...................
Thank you sir nice
Thank you very very much sir . this lecture helped me in getting very close to the topic. thank you sir.
Thanks
How did he discover charge to mass ratio when when charge and mass were not discovered
Why is H taken over B
Really helpful.
Perfect....
The electrons are not comming from the gas..the are actually comming from the copper plate of the cathode...
wonder if this is true? any answer pls?
Yes.the electrons are not coming from the gas. They are coming from the cathode
fast moving electrons excite the gas in the tube, causing a glow between the electrodes
Excellent 99.9%
👏
What is the meaning of this dimensional ratio? 😎
thankyou sir for great explanations i got my douts cleared. and plz upload more videos on all topics it really helps students like us a lot.
v.v v.v nice
good
very gud
If we remove H then v will not be equal to E/H
Thank you for your help sir
Didn’t understand how he measured de magnetic field and electric field
It is more useful for me
There is gravity also
I m thoroughly confused by this video to be very honest .....When u have no magnetic field how can u use the equation v=E/H which was due to cancellation of Electric and magnetic fields but when magnetic field is present no electric field will be cancelled .....How are u using that equation here?

carry on sir...
Ya experiment newton eguation sa assan h sir ji u to balak aa na fuddu bnan alla kam ha ji

Great effort but you can't cleared all dout so don't try
your voice is like sambit patra

Tooo slow
are you mad?
I think your the last bencher in your school 😂😂
Can you speak Hindi
thank you sir
good
thank you sir
