Complete, compact, and stable
This LEAI-45 experimental apparatus is designed to determine the specific charge of an electron, i.e. charge/mass ratio (e/m), based on the longitudinal magnetic field focusing method. It is an ideal teaching apparatus for physics laboratories at colleges and universities. The instruction manual contains experimental configurations, principles and step-by-step instructions.
