Notification

This course does not run anymore, and has been superseded by the new course Electrodynamics 2 (BMETE15AF48) which contains both the lecture and practice courses as a single unit. For up-to-date information cf. the page Electrodynamics 2 (BMETE15AF48). You can find the information for the old course below.

Informations

This course is the practice accompanying the lecture course Electrodynamics 2. There are 10 sessions involving problem solving, and 3 sessions in which mini-projects are reported. Mini-projects consists of sources on a given topic assigned for homework, which are reported in a short seminar type presentation.

Course requirements

After each problem solving session a problem sheet for homework is assigned. Starting from the second week, there is a short (15 minute) test at the beginning of each problems solving session, chosen from marked problems of the previous homework. It is possible to retake three of arbitrarily selected short tests at the time on the 20th May.

Minimum credit requirements:

• absence at no more than 30% of classes (at most 4 occasions of 13);
• a score of at least 40% at the short tests (summed), and each of written tests 1 and 2;
• at least one mini-project presentation.

Evaluation

The total score is a weighted average of the following items:

The mark is computed using the following scale:

Students who failed at the final evaluation have a last chance to gain a pass, provided they have 

• achieved a score of at least 40% at the short tests;
• achieved at least 40% at either written test 1 or 2; and
• have presented at least one mini-project.

The last chance consists of another test on the topic of the written test 1 or 2, depending which one they failed and the result replaces that of the failed test. To gain a pass this must make their total score reach the minimum 40%.
