This course unit provides students with a framework for applying advanced concepts and techniques learned throughout its course, with an emphasis on differential and integral vector calculus, while granting him a background on the field of electromagnetism. This background will enable the student to better understand the world, its constituent parts and interactions between them.

Electromagnetic Field
Electric current
Electromagnetic waves

Using suitably the physics-mathematical language to structure and express opinions.
Applying physic concepts, principles and theories to problematic situations of the real world.
Searching, selecting and organising information to later turn into applicable knowledge to daily phenomena.
Adopting scientific strategies suitable for problem solving and decision making.
Performing activities in an autonomous, responsible and creative way, in a collaborative environment.
