Magnetic coils are placed in pairs on the outside of the CRT to provide horizontal and vertical magnetic fields perpendicular to the electron flow. Current in these coils causes deflection of the electrons perpendicular to the magnetic field and to the direction of the electrons.

• Magnetic Effect Deflection Apparatus consisting of a Cathode Ray Tube mounted to a sturdy base.
• Used to demonstrate the deviation of cathode rays using a magnet.
• Running cathode rays are visible to naked eye by the glowing path on fluorescent screen. When a magnet is brought near deflecting path cathode rays is visible. Fitted on a plastic base and supplied without magnet.
• Cathode Tube is 10" long with a 2" diameter. Apparatus stands approximately 6" tall when assembled.
• Fitted onto a sturdy base. Magnet not included.
