Composition of matter and classification. Insulating materials: polarization, electrical conduction, dielectric losses, and overview of breakdown in gases, fluids and solids. Thermal and mechanical properties of insulating materials. Gaseous, liquid and solid materials and their use. Semiconductors: chemical elements and compounds. Supplements in semiconductors and their influence to conducting behavior. Conductors: conductivity. Conductor materials and their use. Magnetic materials: magnetization process and losses. Soft and hard magnetic materials. Permanent magnets and their use.

• Gives scholarship about main processes in electrical materials (insulating materials, semiconductors, conductors and magnetic materials) in electric and magnetic fields and about use of materials in high-current equipment;
• Gives knowledge for measuring and testing of different materials in electric and magnetic fields.

1. Describes classification of materials on the basis of electrical and magnetic properties.
2. Describes electrical and magnetic properties of substance.
3. Student describes electric conduction mechanism in semiconductors.
4. Describes conduction in materials and influence of different factors to materials conductivity.
5. Describes properties of magnetic materials in magnetic field.

Lectures, individual work, tests, laboratory and homeworks.

The course ends with an examination. Positively executed tests, individual work and laboratory works are the prerequisites of the exam. The final grade is the grade of exam.
