## Module content and teaching

###### Principal aims

To introduce the elementary properties of electrostatic and magnetic fields, and their interaction with dielectrics, conductors and magnetic materials. To introduce some of their practical effects and the behaviour of simple passive circuits and networks.

###### Principal learning outcomes

At the end of this module you should: Understand more about the concepts of charge, field and flux; Be able to compute the electrostatic and magnetic fields for simple distributions of monopoles or dipoles; Understand in outline the interaction between electrostatic or magnetic fields and different classes of material (dielectric materials, dia-, para-, and ferro- magnetic materials); Understand the phenomena of capacitance and inductance; Know the laws of electromagnetic induction and be able to apply them to calculate self- and mutual inductance. You should understand the behaviour of electricity generators and electric motors, and be able to find the energy in simple magnetic fields; Understand the phenomenon of resistance and be able to calculate the current and potential distributions in simple DC networks; Know how the various passive circuit elements (resistors, capacitors and inductors) behave when subject to alternating emf's and be able to use complex impedances to simplify such problems; You should be able to explain the properties of simple LCR circuits.

###### Other essential notes

This module is largely concerned with the great developments in electricity and magnetism, which took place during the nineteenth century. The origins and properties of electric and magnetic fields in free space and in materials are tested in some detail and all the basic levels up to, but not including, Maxwell's equations are considered. In addition the module deals with both dc and ac circuit theory including the use of complex impedance.
