2B29

1. Revise 1B26, especially electrically polarised media and displacement, leading to

D(r ) ≡ (ε 0 Ε(r ) + P(r ))

2. Study magnetic materials, based on magnetic effects of

 B(r )  dipole loop currents; leading to H(r ) ≡  − M (r )  ; µ0   para- dia- and ferromagnetism. 3. Understand simple electromagnets, stored energy in fields, forces generated by magnets. 4. Find inadequacy of Ampere Law. Add displacement current Spring 2004. 2B29 Summary
