Magnetic Deflection of an Electron Beam

Designed to observe how an electron beam is affected by a magnetic field. The power supply holds a deflection tube with a cathode and an anode. The cathode end features a phosphorous coating, which glows when exposed to electrons. As we bring a magnet (not supplied) near, it causes the electron beam to move in a perpendicular direction to show the deflection of an electron and how a cathode and anode both work.
