The Digital e/m Apparatus is a great way to demonstrate Lorentz Force!

Designed to be compact and in a light-shielding enclosure, the Digital e/m Apparatus which is also commonly known as a “Lorentz Force Demonstrator” is used to show magnetic and electrostatic deflection, measure e/m, and investigate electron beam behavior.

The Digital e/m Apparatus has a sharply focused electron beam that is projected into a vacuum containing a trace of inert gas. Ionization of the gas around the electron beam maintains the sharp focus of the beam and creates a glowing discharge which marks the path of the electrons. The apparatus shows deflection of the beam by transverse electric fields and by magnetic fields of various orientations.  The e/m value can be found by bending the electron beam into a circular path with a homogeneous magnetic field and measuring the radius of the circular beam path, the strength of the magnetic field, and the accelerating voltage of the electron gun.
