Informačný list ECTS Sylabus

Slovenština Angličtina

University:

Slovak University of Technology in Bratislava

Faculty:

Faculty of Electrical Engineering and Information Technology

Course unit title:

Applied Magnetism

Course unit code:

I-AMAG

Mode of completion and Number of ECTS credits:

Exam (6 credits)

Name of lecturer:

doc. Ing. Elemír Ušák, PhD. (instructor, lecturer, person responsible for course) - slovak, english

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..).

Prerequisites and co-requisites:

none

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.
