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

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

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

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

  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
