Electricity and Magnetism

This course examines the basics of the electromagnetic field in its static and stationary (slowly-varying) states. The course starts by summarising some fundamental prerequisites by insisting on their specific role and impact in the description of electromagnetic field phenomena. The electrostatic interaction is defined by starting from the electric charge (fundamental electric property of matter), the Coulomb force and electrostatic field. It then introduces the ensemble field description via Gauss's law. The energetic description of the electrostatic field is firstly given in terms of the electric potential, then the electrostatic energy (density) is defined and, finally, the capacitors (as energy storage devices) are examined. The description of the electric state is rounded off by introducing the electric current, in its classical interpretation. The second half of the course concerns the magnetic interaction that is firstly evidenced via the pertaining forces and the manners in which the field is produced. The effect of the presence of matter is briefly touched upon. The fundamental laws governing the magnetic interaction, namely Gauss's law, Ampère's law and Faraday's law are discussed at length, together with some pertaining practical applications. The course ends by highlighting the need for an integrated electromagnetic field description in terms of Maxwell's equations.

This course has:

• 6 Graded Homework Assignments (GHAs), handled via a TU Delft platform; the GHAs yield a sliding-weight bonus for the exam (see below)

• two written partial examinations, (weeks 3.5 and 3.10);

• a resit.

The final grade of the course consists of the following components:

• the written exams grade (denoted as E): (i) the average of the written partial exam 1 and the written partial exam 2; (ii) the grade of the resit; this grade ranges from 1 to 10;

• the result of the GHAs (denoted as B); it is calculated as the average of the results of all but one of the GHAs, in which any non-made GHA is graded with a 0; either the least-scoring GHA (when all GHAs were done) or a non-made one are omitted from the average; this grade ranges from 0 to 10.

The two grades are combined according to the formula:

C = E + B * (10-E) / 100

with C being rounded to half points → this result is recorded in the catalogue.

Applicable conditions:

• To pass the course, a rounded-off, final grade C of at least 5.76 points in scale 1–10 is needed.

• The GHAs result is valid for the partial exams and the resit, but only in the year the assignments have been made.

• The resit includes the contents of both partial exams.

• The result of the partial exams expires for the resit and is not transferable to the next academic year.

• Rules applying to the GHAs: (i) students are allowed to collaborate, but each student is responsible (being a sole author) for the content of the submitted deliverables, which must also be self-written; (ii) when applicable, the deliverables must specify the type of collaboration, and, whether and which AI-(writing)tools have been used, and how they were used; AI tools are not allowed to generate text, or code, or to interpret findings or results; (iii) more course-specific information and guidelines will be provided on the course specific Brightspace page.
