Electromagnetism

Module overview

Electromagnetism is one of the brilliant successes of nineteenth century physics and the equations formulated by Maxwell are believed to account exactly for all classical electromagnetic phenomena. The aim of this course is to present the laws of electromagnetism, their experimental justification, and their application to physical phenomena.

Linked modules

Pre-requisites: PHYS1011 and PHYS1015 and PHYS1022

Assessment

Assessment strategy

Course work worth 20% of the module mark will be set and assessed in the normal way. In the event that a course work is missed, students will be required to go through the Special Considerations procedures in order to request mitigation for that piece of course work. Please note that documentary evidence will normally be required before these can be considered. The final exam is worth 80% of the module mark. Referral Method: By examination, the final mark will be calculated both with and without the coursework assessment mark carried forward, and the higher result taken.

Summative

This is how we’ll formally assess what you have learned in this module.

Breakdown
Method	Percentage contribution
Examination	80%

Referral

This is how we’ll assess you if you don’t meet the criteria to pass this module.

Breakdown
Method	Percentage contribution
Coursework marks carried forward	20%
Examination	80%

Repeat

An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
