Crookes Cathode Ray Tube & Magnet

This particular tube, also known as a "beam deflection tube" was designed to illustrate how a cathode ray beam could be deflected by a magnet. A thin beam of cathode rays is projected through the slit at one end of the tube and strikes a slanted metal plate, which has been covered with a phosphor to produce a visible line discharge. When a magnet is brought near the tube, the effect of the magnetic field can be seen in the deflection of the cathode ray beam.

@JewTown13 what would happen if you put the (+) side of the magnet inside of the cathode ray tube?

Kool !

@goodnight4u the electron beam would disappear. it needs to be in an evacuated chamber to work properly.

Something i always wonder. Now i know that something bad happens but what Exactly would happen if you break the glass while that is operating?

These tubes were probably directly responsible for the vacuum tube amplifiers, tv camera and receiver tv set / display, x-ray's for hospitals, etc. Crooke deserves lots of credit.

[GNVVisalright]

the beam is deflected by the magnetic field. Crooke rules!

[canibuswp]

so are those electrons traveling through a tube? if so, why are they traveling and then bending?

[awfargit]

experiment with the same tube around the magnet / voice coil of a speaker playing lots of bass.......

HUH?

i belive that agent bong meant smart-ass,

cause you certiainly represent a member of the latter class
