Brief description

This module builds on the foundations laid in PH125020, 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, transmission lines, Maxwell's equations.

Content

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

Electrostatics:
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 in differential form, magnetic vector potential, Biot-Savart law, magnetic flux, magnetisation, magnetic intensity, boundary conditions for B and H, hysteresis.

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

Alternating Currents:
Phasors, resonance.

Transmission Lines:
Wave propagation on lossless line, practical lines, reflections, input impedance, matching.

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