Learning activities and teaching methods
Monologic (reading, lecture, briefing), Individual tutoring, Practical training
  • Class attendance - 26 hours per semester
  • Preparation for classes - 20 hours per semester
  • Preparation for credit - 10 hours per semester
Learning outcomes
The course enlarges and strengthens elementary knowledge in the area of electricity and magnetism with emphasis on complex mathematics description. Furthermore, more complicated physics problems examples and physics application will be practice, too. The course follows lecture of electricity and magnetism, but partial phenomena are discussed extensively using consistent and complete mathematical formalism.
Students are able correctly describe phenomena from electricity and magnetism from the point of physics as well as mathematics. Students are also able to solve more complicated practical examples using a complex mathematical apparatus.
Prerequisites
basic knowledge of advanced parts of mathematics - differencial and integral math, knowledge of electricity and magnetism
