Course introduction
To make the students familiar with the fundamental concepts of electromagnetism by providing them with theoretical insight from text and problems and with hands-on experience in the laboratory. In this way both the course provides a basis for understanding and applying electrical-, electronic- and optical components in modern technology.

Expected learning outcome
Upon completion of this course the student will be able to:
• Describe forces between charges and derive mathematical expressions for electric fields originating from different types of charge distributions, of different symmetry, applying integration methods.
• Explore Gauss’ law to calculate electric fields from symmetric charge distributions.
• Derive mathematical expressions for electric potentials of different types of charge distributions, with different symmetry, using integration methods.
• Describe the effect of resistors and capacitors in DC circuits including the energy conversion when connecting a battery in such a circuit.
• Describe and account for the effect of dielectric materials placed in an electric field including the effect on the capacitance of a capacitor.
• Discus magnetism in terms of common magnetic effects and magnetic poles and the compass as indicator of the direction of a magnetic field.
• Describe the force of a magnetic field on a moving charged particle (the Lorentz force) and calculate the force on pieces of a conductor, with different symmetry, in which a current is flowing.
• Discuss the observation first made by Ørsted that a current in a wire produces a magnetic field circulating around the wire, and derive an expression for the strength of this field as a function of the distance from the wire. In addition to this the student will also be able to describe mathematically the magnetic field in space from different current loop structures, like a coil.
• Discuss Amperes law and explore it to express mathematically how different current loops produce magnetic fields, like the case of a coil.
• Discuss the law of induction (Faraday) based on the concept of magnetic flux density and how a change of the total flux density through a closed electric circuit (a loop) induces an electric current in the loop.
• Understand the physical concepts expressed by Lentz’ law and some typical applications of it.
• Describe how different types of magnetic materials behave under the influence of an external magnetic field.
• Continue studies of electromagnetism in the course FY506.

Prerequisites for participating in the exam
None

Assessment and marking:
(a) Labwork, pass/fail and internal marking by the teacher. The labwork, which accounts for 1 out of 5 ECTS should be passed to attend the written exam.
(b) A 4 hour written exam, which counts for 4 out of 5 ECTS with external censorship and grades according to the Danish 7-point scale.

Re-examination after 2nd quarter.

Expected working hours
The teaching method is based on three phase model.

Forelæsninger (20 timer), eksaminatorier (20 timer) og laboratorieøvelser (9 timer).
