### Offering and execution

Course offering missing for current semester as well as for previous and coming semesters

## Course information

### Content and learning outcomes

#### Course contents *

Part 1: Static fields.

Electrostatics: Coulomb's law. Electric lines of force. Evaluation of electric field and potential in vacuum and with conducting and dielectric materials. Capacitors. Energy and force in electrostatic systems. Conductors and semiconductors.

Magnetostatics: Static magnetic fields. Biot-Savart's and Ampere's laws. Fields in magnetic materials. Magnetic circuits and reluctance.

Part 2: Time-dependent fields.

Electromagnetic induction. Faraday's law. Mutual and self-induction. Energy and forces in static and quasi-stationary fields. Maxwell's equations. Conservation laws. Radiation and reception of electromagnetic waves. Transformation of electric and magnetic fields between systems with uniform velocity.

#### Intended learning outcomes *

When the students have passed the course, they shall:

• be able to describe the relation between electromagnetic fields and their sources (distributions of charge and current)
• understand how isotropic materials affect the field distribution
• know Maxwell's equations (on differential and integral form) and how to use them
• be able to analyse plane waves and also fields from given current distributions
• understand retarded potentials and fields
• be able to choose adequate models and methods of solution for a specific problem
• have good ability to solve problems analytically and numerically.
