• Flux (for measuring total current)
  • Charge Density (for comparison with current density, and/or as an quantity that contributes to current density)

In-class Content

  • Acting Out Current Density (Kinesthetic Activity - 10 min) Note: Curl is needed for 3 different ideas in this class: Conservative Work, Going from $\vec A$ to $\vec B$, and getting from $\vec B$ to $\vec J$.
  • Current Density (lecture) 10 min

Homework for Static Fields

  1. (TotalCurrentGEM55) Calculate surface current density $K$ and volume current density $J$ for a wire carrying total current $I$, from Griffiths E&M book.
