Electricity & Magnetism: E/M Tube

PIRA Class: 5H30.20

Purpose: 

To demonstrate the force on charges (and subsequent change in the motion of the charges) moving perpendicular to a magnetic field. 

Description: 

A beam of free electrons is bent into a circular/ spiral path by large Helmholtz coils.

- To observe the effect of the external magnetic field on the moving electrons, vary the strength of the current in the Helmholzt coils and the initial direction of the electron beam. 

Equipment: 

E/M Tube, Power Supply, Lead Wires
