Surely the particle will accelerate along the way? We have to assume the distance travelled in the velocity selector is small, and that the velocity is constant in the selector?
+Charles Goh at 0:40 he explains that only particles travelling at a specific velocity will make it out of the velocity selector. this is because of the deflection due to the magnetic field in the selector.
Hy sir, I would like to ask you, what if we accelerate the particle before entering the magnetic field, I mean if we have variable velocity, what should we do to get v ? we suppose v(0)=0.. thank you
The acceleration only occurs PRIOR to the charge entering the magnetic field. Once the particle enters the magnetic field, the magnitude of the velocity remains constant.
@@MichelvanBiezen Ah okey, now i get that even if i add a voltage difference source before the magnetic field, I will still work with a constant velocity, Got it sir, thank you very mush.
Hi Sir, I have a question about electric fields and I was wondering if you knew the answer as I cannot find it online. Do electrons (or any charged particle for this matter) get deflected more or less when their velocity is greater? The situation that I'm referring to is when an accelerated beam of electrons enter an electric field and then follow a parabola kind of shape.
Thank you for this video but still i have a question, Particles with different masses will also have different radii thus different velocity so they will deflect not entering the circular motion part so does that mean that the spectrometer only measures one type of particle at a time?
@@MichelvanBiezen Thanks for replying,I have another question.When the electron enters the magnetic field why will it have to move exactly a half circle until it reaches the screen why not less or more?
This makes so much sense; thank you!
Great video, and love the bow tie!
Thank you!
Such a great video, thank you
Thank you. Glad you find it helpful.
You're a saint Michel

That is correct.

The effect would be the same as with a magnetic field. The faster they travel, the greater their turning radius.
Michel van Biezen thank you :)

Typically, the velocity on entry of the spectrometer is controlled and adjusted for particular particles.

It will move in a circular path until it hits a target. (which is placed when it covers a half a circle.)
can you please do a "Mass Spectrometer" video with velocity that emerge into a magnetic field? Please
Tomorrow i will be having physics exams. smh
There already is a video on this: Physics - E&M: Magn Field Effects on Moving Charge & Currents (20 of 26) The Mass Spectrometer
yea i saw it... but i wonder if you can explain more by doing another video
