| 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
Students will be able to demonstrate knowledge, understanding and application of:
1. Electric and Magnetic fields, Biot-Savart law for a point charge and Lorentz force;
2. Maxwell’s Equations both “microscopic” and “macroscopic”;
3. Electric and Magnetic potential, Poisson’s equation;
4. Wave equation, EM waves, EM Spectrum and the Poynting vector;
5. AC circuits (LCR), complex impedance, transients, resonance.
Skills outcomes
