Lecture 15, ACT 1

Two cylindrical conductors each carry current I into the screen as shown. The conductor on the left is solid and has radius R=3a. The conductor on the right has a hole in the middle and carries current only between R=a and R=3a.
- What is the relation between the magnetic field at R = 6a for the two cases (L=left, R=right)?
