## Learning outcomes

Electromagnetism is a fundamental part of classical physics with considerable technological applications. The course constitutes a basis for further studies in physics, electrical engineering and materials science.

On completion of the course, the student should be able to:

• performing calculations of electric and magnetic fields in space in some selected geometries with boundary conditions.
• performing calculations of stationary and time-dependent electrical currents in selected circuits containing resistors, capacitors, and inductors.
• accounting for the operational principles of common electrical devices.
• handling the most common instruments for electrical measurements.
• account for basic theories in electrostatics, electrical circuits, stationary electromagnetism and electromagnetic induction,

## Content

Electrostatics: electric charge, Coulombs law, electric field strength and potential, superposition contributions from point charges, Gauss' law, electric dipoles, capacitance, polarisation, dielectrics, electrostatic energy and capacitors.

Electric current and theory of circuits: current density, Ohm's law, Kirchhoff's laws, Joule's law, electromotive force (EMF), charging and discharging of capacitors, circuit analysis.

Magnetic fields: flux density, magnetic forces, Biot-Savart law, magnetic dipoles, Ampere's law on integral form, magnetic polarisation and an overview of magnetic materials.

Electromagnetic induction: Faraday's och Lenz' laws, inductance. LR cicuits, the energy of a magnetic field, mututal inductance.

Maxwell's equations.

Overview of electric current, effect, safety considerations in electricity and the ideal transformer.

## Instruction

Lectures, problem solving sessions and laboratory work. Guest lecture.

## Assessment

Laboratory exercises (1 credit)
Written examination at the end of the course (4 credits) and a non-compulsory half-time examination. Passing the half-time examination will give the student a bonus which is only valid at the final examination at the end of the course and at the first scheduled re-examination.

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
