After taking this module students should be able to:
- apply the differential operators of vector calculus to electromagnetic problems.
- describe the four basic laws of electromagnetism and their applications.
- explain the effects of matter on electric and magnetic fields and the boundary conditions for such fields.
- solve problems on resonance in alternating current circuits.
This module presents the concepts of electromagnetism in terms of vector calculus. Topics covered include electrostatics, dielectrics, magnetic fields, magnetic fields in matter, electromagnetic induction, alternating currents and resonance, Maxwell's equations.
Grad, div, curl, divergence theorem, Stokes' theorem, vector identities.
Electric charge and field, Gauss' law, electrostatic energy, potential, capacitors, dielectrics, polarisation, electric displacement, boundary conditions for D and E, Poisson's equation, electrostatic calculations.
Lorentz force, magnetic dipole, Ampere's law, magnetic vector potential, Biot-Savart law, magnetic flux, magnetisation, magnetic intensity, boundary conditions for B and H, hysteresis.
