### This module is mutually exclusive with

PHYS2300 | Physics 3- Fields and Energy |

PHYS2350 | Electromagnetism (Joint Honours) |

**This module is not approved as a discovery module**

### Objectives

By the end of the module you should be able to:- use the integral versions of Maxwell's equations to explain the concepts of electric fields and potentials, magnetic fields and magnetic induction, and to calculate these fields in cases of simple symmetric geometry.

- calculate the force on a moving charge in an electric and magnetic field and the force on a current carrying conductor, and to calculate the energy stored in electric and magnetic fields.

- analyse simple AC circuits containing resistors, capacitors and inductors.

- state Maxwell's equations in both integral and differential form and discuss their derivation from the physical laws of electromagnetism, in vacuo and in dielectric and magnetic media.

**Learning outcomes**

Demonstrate a basic knowledge and understanding of common physical laws and principles, and some applications of these principles.

Identify relevant principles and laws when dealing with problems.

**Skills outcomes**

Problem solving in electromagnetism
