Slovak University of Technology in Bratislava
Faculty of Electrical Engineering and Information Technology
Course unit code:
Course unit title: Applied Magnetism
Mode of delivery, planned learning activities and teaching methods:
2 hours weekly (on-site method)
laboratory/construction practice
2 hours weekly (on-site method)

Credits allocated: 6
Recommended semester/trimester:
Applied Electrical Engineering - master (semi-compulsory), 3. semester
Level of study: 2.
Prerequisites for registration: none
Assesment methods:
During the semester there will be one written test for 12 points. The student obtains a maximum of 18 points for the experimental exercises and written report of obtained outcomes of these exercises. Students must complete all the exercises. For the exam, a student can earn a maximum of 70 points. The maximum score for the entire course is 100 points. Final evaluation of the student's mark is in accordance with actual study rules.
Learning outcomes of the course unit:
By completing the course the students obtain basic information from the field of physical phenomena and processes arising in magnetic materials as well as knowledge of the classification of substances in terms of their magnetic properties. The students will learn basic methods of evaluating the properties of such materials with respect to the requirements of specific applications in the field of electrical engineering (e.g., electrical machines - transformers, generators, motors, etc..).
Course contents:
Basic terms and physical quantities ​related to the electromagnetic field, Maxwell's equations in integral and differential form. Material relationships, magnetic permeability and susceptibility, complex permeability. Atomic magnetism. The classification of substances according to magnetic properties. Substances without a magnetic structure and with disordered structure, diamagnetism, paramagnetism. Substances with an organized structure, ferromagnetism, antiferromagnetism, ferrimagnetism. Magnetic anisotropy and its classification. Magnetostriction (Joule effect) and its categorisation. Magnetoelastic (Vilari's) phenomenon and its relationship with magnetostriction, magnetoelastic energy. Domain structure of ferromagnets. Methods of magnetic domains observation. Magnetisation processes, domain walls motion, magnetic polarisation vector rotations, paraproces, saturation magnetic polarisation. The mechanism of magnetisation (formation of magnetic reversal nuclei), reasons for magnetic hysteresis. Basics of measurement of magnetic properties of massive samples. Methods of sample demagnetization.
