LEAI-45 Determining Specific Charge of Electron - Basic Model

Features

  • Complete, compact, and stable

  • Affordable






Introduction

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. Please click Experiment Theory and Contents to find more information about this apparatus.
