Abstract
This NANSLO lab activity is self-contained and can be used in physics courses. In this activity, a gas discharge tube and a pair of Helmholtz coils are used to examine the motion of electrons in a magnetic field. The lab activity includes background information on how these instruments are used to examine the motion of electrons in a magnetic field and provides equations that are used to measure the ratio of the electron charge to the electron mass by determining the potential difference used to accelerate electrons, the magnetic field strength, and the radius of the circular motion of the electron. The lab activity also includes a pre-lab exercise, lab exercises, data analysis activities, and an optional advanced analysis activity.
