K1-14. Oscilloscope Crt - Deflection By Magnet
Purpose
To demonstrate magnetic deflection of an electron beam.
Equipment
CRT with power supply and small bar magnet.

Description
The beam of an oscilloscope CRT is viewed at the front on the fluorescent screen in the standard way. Holding a magnet near the CRT such that the magnetic field is perpendicular to the path of the electrons creates a magnetic force on the electron beam which deflects the beam, as can be seen on the fluorescent tube.
