PHYS1004 Physics 1 (Environmental) – Semester 2, 2016
MODULE 1 OUTLINE: ELECTRICITY AND MAGNETISM
Unit Description
This module is one of 3 comprising PHYS 1004 Physics 1 (Environmental). This document describes details of
this module and should be read in conjunction with the more general unit of study outline for PHYS 1004
Physics 1 (Environmental).
General goals of this module
This lecture module aims to develop the ideas of electricity and magnetism and illustrates their practical
applications in the environmental and life sciences. The module investigates the concepts of charge,
conservation of charge and the forces between charges. The module also investigates the nature of electric
and magnetic fields, and how they can be produced and the interactions between them.
MODULE DEFINITION & OBJECTIVES – ELECTRICITY & MAGNETISM

Field, 3rd edition published by Pearson/Addison Wesley, 2007.)
LEARNING OBJECTIVES
For each topic in this Module the Specific Objectives define what we expect you to learn and understand.
“Understanding” a term or concept means that you should be able to:

explain its meaning,

interpret it correctly when you read or hear it,

use it correctly in your own writing.

apply it correctly to examples and problems.
There is no easy road to learning. Your marks will depend on the work that you do. You should therefore read
through and understand the sections of the textbook specified below, and work through the specified
examples. You should then attempt as many as possible of the recommended questions, exercises and
problems. Problem solving skills can only be acquired by practice.
This module is also supported by some web-based material accessible through the eLearning page for this
unit.
