1. Hall Effect
Form 6
Physics

2. PowerPoint Presentation
Chung Sai Chak

3. 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.

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

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

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

7. Finally...
B-field V H I

8. How to calculate the Hall voltage?

9. 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?

10. Thank You
