Description: Aims:
The aims of this unit are to introduce the fundamental laws of electricity and magnetism and to develop techniques used in the solution of simple field problems, both vector and scalar.

Learning Outcomes:
After taking this unit the student should be able to:
* state the basic laws of electricity and magnetism;
* define scalar and vector fields and represent them graphically;
* determine the forces due to electric and magnetic fields acting on charges and currents;
* determine electric fields, potentials and energies due to simple, static charge distributions;
* determine magnetic fields and energies due to simple, steady current distributions;
* determine electric fields, e.m.f.s and induced currents due to varying magnetic fields.

Skills:
Numeracy T/F A, Problem Solving T/F A.
