Description

Advanced physics items are drop shipped. These products are built to order. Carolina does not hold stock. Please allow 90 days to receive your item from the time you place your order. This is the industry standard for this type of equipment.

Measure the electron charge to mass ratio (e/m) and study the electric and magnetic properties of an electron beam with this compact device based on a built-in CRT. Included are all the accessories needed to explore electron beam deflection, focusing, and electron behavior in transverse and axial magnetic fields. The Complete Properties of Electrons Apparatus is self-contained. All high voltages are enclosed internally for safety. The built-in displays eliminate the need to connect external multimeters.

The instruction manual contains sample activities and sample data for the following basic experiments:

  • Electron behavior in an electric field
  • Electron deflection in a transverse electric field
  • Electron paths in an inhomogeneous longitudinal electric field
  • Electron behavior in a magnetic field
  • Electron deflection in a transverse magnetic field
  • Spiral electron path in a longitudinal magnetic field
  • Determination of e/m

The Complete Properties of Electrons Apparatus is all that is required for these experiments. No additional accessories are needed.
