### Aims

To develop a basic understanding of electric and magnetic fields in free space using the integral forms of Maxwell’s laws.

### Learning outcomes

On completion successful students will be able to:

1. describe the electric field and potential, and related concepts, for stationary charges.
2. calculate electrostatic properties of simple charge distributions using Coulomb’s law, Gauss’s law and electric potential.
3. describe the magnetic field for steady currents and moving charges.
4. calculate magnetic properties of simple current distributions using Biot-Savart and Ampere’s laws.
5. describe electromagnetic induction and related concepts, and make calculations using Faraday and Lenz’s laws.
6. describe the basic physical content of Maxwell’s laws in integral form.
