Summary

This course follows the Theory of Electromagnetic Field and Electrical Machines 1 courses and completes the knowledges in the range of the electromagnetic circuits applications. The main contents of this course are concentrated on the theory and design of dc and ac attracting and holding electromagnets and on applications of electromagnetical devices in other technical branches (material separation etc.). In the second part of this course a theory of instrument and securing transformers including their design is added to the general theory of transformers.
