Academic preconditions:
Students taking the course are expected to:

• Have knowledge of calculus (MM536) and fundamentals of physics (FY529).

Course introduction
The aim of the course is give the students basic knowledge of fundamental principles behind electromagnetic theories and phenomena.

The course gives an academic basis for studying electric and magnetic phenomena, as well as the topic optics, that are part of the degree in physics without a side subject.

• Give skills in theoretical and experimental examination of specific physical phenomena
• Give knowledge and experience with fundamental theory formation and experimental methods of Physics
• Give competence to participate in professional and interdisciplinary cooperation with a professional approach based on experience with group-based project work

Expected learning outcome

• recall basics of electric and magnetic fields,
• know basic formulae describing the interactions between electric charges, force of magnetic fields on electric charges and electric currents, 
• describe the function and applications of the most common electric components used in direct-current circuits,
• describe expressions for a number of electric and magnetic phenomena via mathematical models,
• describe electric and magnetic properties and behaviour of different materials,
• describe currents and voltages of alternating current circuits,
• describe interference phenomena among harmonic waves in one and two spatial dimensions,
• mathematically describe basic diffraction phenomena. 

• perform computations of electric field and electric potential of different charge distributions,
• explain the function and applications of the most common electric components used in direct-current circuits,
• evaluate expressions for magnetic fields, originating from electric direct currents in conductors, 
• perform calculations of currents and voltages of alternating current circuits including the evaluation of the impedance of different components and different types of circuits 
• explain the physical meaning of Maxwell’s equations and of the physical quantities entering in their definition, 
• explain how an optical microscope works and sketch the imaging and the illumination paths,
• explain the fundamental limitations diffraction phenomena place on resolution of optical/spectral instruments.

• analyse different phenomena of electric and magnetic fields and their effect on charged particles,
• analyse experimental setups that are shown in the course book,
• using  geometric optics, analyze beam paths in optical systems with up to two components,
• report and analyse laboratory experiments in a formally correct and complete way (including discussion).

Expected working hours
The teaching method is based on three phase model.
Intro phase: 46 hours
Skills training phase: 50 hours, hereof:
 - Tutorials: 29 hours
 - Laboratory exercises: 21 hours

Educational activities

• Study of textbook (D. Halliday, R. Resnick, and K. S. Krane, Physics, volume 2, 5th edition)
