LEAI-48 Lorentz Force Demonstrator

LEAI-48 Lorentz Force Demonstrator

Features

  • Complete apparatus

  • Compact and stable

  • Affordable






Introduction

This LEAI-48 Lorentz force demonstrator is useful for testing the charge/mass ratio (e/m) of an electron, and demonstrating the Lorenz force exerted by a magnetic field on moving electrons and the deflection of moving electrons within an electric field. It is an affordable teaching apparatus for physics laboratories at colleges and universities.
