Learning Outcomes

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.

Brief description

This module builds on the foundations laid in PH(FG)12020, and presents the concepts of electromagnetism introduced in the earlier module 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.


Vector Calculus:
Recap, grad, div, curl, divergence theorem, Stokes' theorem, vector identities.

Electric charge and field, Gauss' law in differential form, electrostatic energy, potential, capacitors, dielectrics, polarisation, electric displacement, boundary conditions for D and E, Poisson's equation, electrostatic calculations.

Magnetic Fields:
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.

Electromagnetic Induction:
Faraday's law, inductance, magnetic energy.

Alternating Currents:
Phasors, resonance.

Maxwell's Equations:
Equation of continuity, displacement current, Maxwell's equations.
