Here are the results of the evaluation that we did in Lecture 8. Overall, the course seems to be going well, but with some room for improvement. I will discuss these results with the tutors too. Thank-you for your feedback!

Supplementary Material

Today's demonstrations: (i) electric forces with charged pith balls and a balloon; (ii) magnetic forces between two bar magnets; (iii) electric field due to a dipole charge configuration; (iv) magnetic field (seen by four compasses) produced by an electric current;

Today's animations:

• Flash animation of electric field lines for a positive point charge: http://www.upscale.utoronto.ca/GeneralInterest/Harrison/Flash/EM/FieldLines/FieldLines.html

• Magnetic field lines of a bar magnet seen in iron filings: http://micro.magnet.fsu.edu/electromag/java/magneticlines/index.html

• Magnetic field lines between two bar magnets: http://micro.magnet.fsu.edu/electromag/java/magneticlines2/
