Introduction
The LEAI-45 experimental apparatus is specifically designed for measuring the specific charge of an electron (i.e., the charge-to-mass ratio (e/m)) using the longitudinal magnetic field focusing method. This method allows for the precise determination of the electron's specific charge by analyzing its trajectory in the presence of a magnetic field.
The apparatus provides a straightforward setup for teaching the principles of electron motion in magnetic fields, which is fundamental in electromagnetism and modern physics. It is an ideal tool for college and university physics laboratories, offering both ease of use and accurate results.
The instruction manual contains experimental configurations, principles and step-by-step instructions. Please click Experiment Theory and Contents to find more information about this apparatus.
