Course objectives
This lecture is basic course of Electricity and Magnetism for first year students. At the end of this course, the student obtains the knowledge of basic laws of electricity and magnetism, he will be able to calculate the electric strength and magnetic induction for electric and magnetic fields and the their action on charges. He obtains the basic knowledge of mutual action of electric and magnetic fields with matter. Furthermore he will be able to solve the problems from electric circuit theory.
Learning outcomes
The student will be able:
- to solve the problems in the field of electric and magnetic fields;
- to the problems in the field of electric circuits.
