The document is a PowerPoint presentation introducing the Hall effect to Form 6 students weak in abstract concepts. It uses semiconductor slices to demonstrate how the Hall effect works, showing that when a magnetic field is applied perpendicular to the current in a slice, it causes the electrons to deflect and accumulate on one side, creating a Hall voltage. The presentation calculates the Hall voltage and asks questions to check understanding of what the Hall effect is, why semiconductors are used, and applications of the Hall effect.

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 ... qBv B-field I

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

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

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?
