ObjectivesBy 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;
Thermodynamics and Statistical Physics
- give examples of the emergence of thermodynamic phenomena in systems with large numbers of particles;
- use the Boltzmann factor to calculate occupation probabilities of states;
- use Boltzmann, Fermi-Dirac or Bose-Einstein statistics as appropriate to discuss basic thermodynamic properties of the two level paramagnet, the degenerate electron gas and blackbody radiation;
- discuss the concept of entropy from both the thermodynamic and statistical points of view and calculate entropy changes in irreversible processes;
- define enthalpy, the Helmholtz function and the Gibbs function and discuss their utility;
- state and discuss the four laws of thermodynamics, including various alternative formulations of each law;
- use these laws, and Maxwell relations to solve simple thermodynamic problems;
- describe the phase diagram for a one-component system, derive the Clausius-Clapeyron equation and use it to solve problems relating to the dependence of a phase transition on temperature and pressure.
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.
