if you read/heard well enough, you'll know that a CRT has "almost" NO gas!!! it is virtually a vacuuum!!! so the electron doesn't collide with anything and can go straight (or deflected) from the electron gun to the screen
in a CRT, a material is heated untill the electrons have enough energy to become free from his atom's orbit, then, an electric field makes it accelerate. Depending on the polarization of that field, it can go one way or another in a straight line. A magnetic field will deflect it, In fact, an electric field will accelerate an electron in a straight line (it will change the magnitude of velocity), while a magnetic field will make the electron change direction.
@RUS38 , NO there are not such things as contiguous north pole magnets which are accelerated. That would indicate that infinitely small subatomic, rectangular magnets would orbit the nucleus, and that my dear good man is preposterous, and ignorant. Oh, and I would suppose that supper-symmetrical strings reverberate as rectangular entities themselves.
I'm quite concerned of the general nescience of these commenters. In order to ameliorate themselves, I highly advise learning legitimate physics. Electrons are legitimate entities,( as stated by the clip ). Electrons orbit the atom. Electrons loosely orbit the valence orbit, in which the "free electrons" accelerate towards "holes". These are ionized atoms, at which when these "free electrons" collide the mercury vapor, or gas, they cause the electrical orbit to recede, and emanate photons.
pretty good :) some people here are talking of the canal ray experiment over here thats when the cathode electrode is kept more over to the centre as a perforated disc and an electrical field placed behind it :)
The connection gave the negative terminal a double dose of strength, and so it became hotter and could push more. It was called cathode and the positive terminal anode, and the electricity that passed from the cathode to the anode was called electrons.
The positive electricity is composed of streams of north pole individual magnets, and negative electricity is composed of streams of south pole individual magnets. They are running one stream of magnets against the other stream in whirling right hand twist, and with high speed. (Edward Leedskalnin). Electrons don't exist. People at schools are misled by same misled teachers and scientists who share information from wrong books. So yes FUCK SCHOOL!
@RUS38 LQL sir xD!!!!! you made my day for making me laugh so hard hahahahahaha XD
When electricity was discovered, they thought it was "positive charges in movement", but it was discovered that it was the oposite: negative charges movement.
Magnets cannot be separated in just a north (or south) magnetic particle
The worst explanation of cathode ray production ever.
Why needed so high vacuum, 1 mTorr? I am tried 1-5 Torr, and still getting cathode rays. That is 1000 to 5000 times the pressure mentioned on this video.
What will happen if magnet is behind the cathode?
Emitting electrons faster? Emitting electrons but in weird motion? Or, not emitting electrons at all?
If the cathode plate sitting in the middle, why then electrons shooting in both directions? To anode, and in the opposite direction?
The Ray is deflected the wrong way when presented the North par of a magnet. The North wil deflect it away from the magnet and the South will attract it.

it amazes me how the ray itself is nothing but electrons...passing through the cathode...i love the equation itself =)
