K1-12 CATHODE-RAY TUBE - DEFLECTION BY MAGNET

ID Code: K1-12
Purpose: Demonstrates the force on an electron beam by a magnetic field
Description: A cathode ray tube produces a beam of electrons which can be seen as it hits a phosphorescent surface inside the tube. Holding a magnet close to the CRT parallel to the table so that it produces a horizontal magnetic field inside the tube causes the electron beam to deflect up or down. The vector nature of the force can be studied by reversing the magnet.
