How

Image on black and white television is deflected by a magnet, not unlike the Maltese Cross.

What it shows:
The television is basically a sophisticated cathode ray tube. The electron beam in the TV is influenced by magnetic fields in the same way as in...

What it shows: 

A collimated beam of Cathode rays can be deflected by a magnetic field.

How it works: 

This Crookes tube has an anode and cathode at opposite ends of a cylindrical tube, with a horizontal slit near the cathode and a vertical fluorescent...

Maltese cross obstacle and fluorescing glass show that electrons in a Crookes tube travel in straight lines and are affected by magnetic fields.

What it shows:

Cathode rays in a Crookes tube are seen to travel in straight lines by casting a sharp shadow of...
