This is a lesson and PowerPoint that covers how to calculate the specific charge of an electron (including both the balanced forces technique and the fine beam method) and should be supported with two recommended demonstrations. There is also an additional supporting document to explain how to correctly set up Helmholtz coils and how to calculate the flux density between them.
The lesson gives ideas for homework, three example questions with work-through answers and gives ideas for experiments linked to the subject (J.J. Thomson’s original experiment plus the fine beam method)
As well as supporting A-Level Physics for many exam boards this lesson is also part of a chapter that covers the optional Turning Points in Physics unit 9 for AQA (Lesson 3 of 13)
