Cathode-Ray Tube Demonstration

A demo of a cathode-ray tube (vacuum tube) with a Tesla coil and a weak magnet. The magnet is easily able to move the cathode ray around.

At what energy level will x rays be created? I want to demonstrate this to my class, but I'm concerned about my tesla coil / CRT combination.

Beautiful. Thank you so much for sharing this with us!!!!

[@ketzbook]

glad you liked it!

This is the Egyptian light bulb

I don't get how this works in this demonstration. This shows only cathode end bein connected to anything. Nothin else is connected. Why electrons decide to flight out towards the anode? Or are they flying out in all directions, but are visible only where they hit phosphorous?

Thanks a lot 🤩 it is obvious

GOOD ONE

Where can one find this tube?

WHY CATHOD BEAM IS NOT VISIBLE AFTER WHITE BOARED

[@ketzbook]

because electrons traveling through a vacuum are not visible. You can only see them when they hit a fluorescent screen.

[@phandinhthanh2295]

The real question here is: what are those fluorescent screens often being used in x-ray experiments made of? I've been always wondering that!

@@ketzbook Hi, do you happen to know why the anode is way over at the other end of the tube? I mean I get that it attracts the electrons over, but it's just that in my physics book it showed the anode as being right over at the side of the tube near the cathode. It also showed the anode as having a hole in it for the purpose of channelling the electrons early on in the tube.

@@1091Floyd21 I think there are a variety of different designs that all work.
