I noticed after recording that a wrong sign appears on the components of the current vector field.
On the web this is corrected and a vector graph is added for the current. I also add a vector graph that
shows better the length of each one, by not requesting that the vectors are normalized.
A solution is only found outside the cylindrical hole. As the origin of the coordinate system is thus avoided components of the
solution that diverge at r = 0 are allowed and needed.

Thursday, February 20
- Lecture 12, Maxwell equations - Wave equations: Wave equations (mp4)
- Problem set 05: Problem set 05 (mp4). In the last line of problem
1 a sinus is missing in the expression for the mangetic field. It is now in the solution outlines.
