More Information
SKU PCL-UN-LFD001

  • The Lorentz Force Demonstrator is a “fine beam tube” device in which a sharply focused electron beam is projected into a vacuum containing a trace of inert gas.

  • Ionization of the gas around the electron beam creates a glowing discharge marking the path of the electrons and helping to maintain the sharp focus of the beam.

  • The demonstrator shows deflection of the beam by transverse electric fields and by magnetic fields of various orientations.

  • The value of e/m can be found by bending the electron beam into a circular path with a homogeneous magnetic field and measuring the accelerating voltage of the electron gun, the strength of the magnetic field and the radius of the circular beam path.
