Learning objectives:
To enable the students to:
1) describe electromagnetic phenomena using the language of vector calculus.
2) determine electric and magnetic fields arising from simple configurations of static charges as well as steady currents in vacuum and in matter
3) solve problems involving the propagation of electromagnetic waves in vacuum and in matter.
