Hall Effect Form 6 Physics

PowerPoint Presentation Chung Sai Chak

Introduction target audience: form 6 student in band 5 school, weak in understanding of the abstract concepts. After introduced what is the Hall effect, use the powerpoint slices to give a lecturing of mechanism of the Hall effect.

When electrons flow without magnetic field... semiconductor slice t d _ + I I

When the magnetic field is turned on ... B-field I qBv

As time goes by... high potential qE I low potential qBv = qE

Finally... B-field V H I

How to calculate the Hall voltage? .....................................................................................................................

Do you know... What is the Hall effect? Why we use semiconductor slice to demonstrate the Hall effect? What is the application of the Hall effect?

Thank You
