## Synopsis

This unit explores electrostatic, magnetostatic and electromagnetic fields, and their use to create devices and systems. Mathematical concepts are used to describe the fields, and examine the basic laws governing the generation of fields and their interactions with dielectric and magnetic materials. This study results in Maxwell's field equations, and related Laplace, Poisson and continuity equations. The real life applications of electromagnetic fields in radio communications and devices such as scanners, printers and mass spectrometers are also explored in this unit. Finally, plane wave propagation is analysed briefly as an extension of Maxwell's field equations.

## Outcomes

On successful completion of this unit, students will be able to:

1. Apply knowledge of mathematics to examine the behaviour of electric and magnetic fields and relate them to suitable applications.
2. Interpret Maxwell's equations and associated Laplace, Poisson and continuity equations using mathematical principles.
3. Describe electric and magnetic properties of metals, dielectrics and semiconductors.
4. Select and use appropriate tools to complete electrical and magnetic fields related laboratory tasks.
5. Communicate their work effectively in teams.

## Assessment

NOTE: From 1 July 2019, the duration of all exams is changing to combine reading and writing time. The new exam duration for this unit is 2 hours and 10 minutes.

Continuous assessment: 40%

Examination (2 hours): 60%

Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.
