Objective

The goal of this course is to give 1st year students aiming for a B.Sc. in Physics and Electronics an introduction to the concepts and guiding principles of Electricity and Magnetism and their applications in the solution of physical problems in a real context. Learning objectives: At the end of this course, the student must be able to: 1. Understand the concepts of electric charges, electric field, electric force and electric flux and to apply Gauss’s Law. 2. Define and calculate the electric potential and electrostatic potential energy. 3. Calculate the capacitance of, and energy stored in capacitors of various forms. 4. Apply Ohm’s law and Kirchhoff’s rules on DC circuits. 5. Determine the magnetic field vector produced by currents and moving charges, through applying Ampere’s Theorem and Biot-Savart law. 6. Study the effects of Magnetic fields on charged elements and current carrying wires. 7. Analyize physical situations and apparatus involving combined Electric and Magnetic Effects.

The meetings include time for discussions and Q&A, making it possible for the students to take an active part in the course flow. Directed Work forms the essential part of the course. The final grade of the course is built up from: 30% partial exam after the first 6 weeks of the semester, and 70% final exam at the end of the 12th week.
