Electron Beam in Magnetic Field

PURPOSE: To demonstrate the magnetic deflection of an electron beam.

The Crookes tube contains a white screen that flouresces green when electrons collides with it. High voltage applied across the anode and cathode accellerate electrons through the tube. The electron beem can be deflected using the magnetic field of a bar magnet.

ALWAYS USE THE MINIMUM VOLTAGE AND CURRENT NECESSARY TO OPERATE THE CROOKES TUBE.
