Intended learning outcomes

After completion of the course a student is expected

• to understand fundamental laws of electromagnetism (Coulomb’s law, Gauss law, Ohm’s law, Amper’s law, Faraday’s law etc. ), as well as fundamental concept such as potential, capacitance, current, resistance, inductance, e.m.f., electromagnetic induction, etc.
• to be able to apply fundamental laws of electromagnetism to perform practical calculations (e.g. calculate potential, electric and magnetic fields, capacitance, inductance, e.m.f., etc. for basic model systems)
• to be able to relate fundamental laws of electromagnetism to various technological applications as well as to everyday life phenomena
• to be able to use the laws of electromagnetism in subsequent courses (such as Modern Physics, Semiconductor devices, Introduction to Material Science, Photonics etc.).

The course aims to give students knowledge of electromagnetism which is essential for continued studies in physics, esp. in the area of electronics.

Course content

• Fundamental theory of electrostatics: Coulombs law, electrostatic potential och field, superposition principle, dipole and generalised multipoles. Brief description of electrostatic fields in conductors and dielectric materials, polarisation and permittivity, Gauss law, Poisson's and Laplace's equations and boundary conditions.
• Fundamental theory of magnetism: magnetic field strength, Biot-Savart law, divergence and curl of magnetic fields. Magnetism in media, magnetisation, para-, ferro- and diamagnetic materials.
• Maxwell's equations and the electromagnetic field. Electromagnetic waves in vacuum, energy density and Poynting's vector.
• EM waves in dielectric and conducting materials: group velocity and the index of refraction. Reflection, refraction and polarisation. Waveguides.
