In this problem, we are interested in the electric field induced in the space by this system. With the harmonically varying source current, the induced electric field will also be changing periodically with the same frequency. You are asked to examine the amplitude E$0($r$)$ of the induced electric field at different distances r from the axis of the system.

What is E$0($r$)$ for r$=$r$1=1\mathrm{.}2$ cm$?$:

E$0($r$1)=0$

What is E$0($r$)$ for r$=$r$2=4\mathrm{.}3$ cm$?$:

What is E$0($r$)$ for r$=$r$3=8\mathrm{.}6$ cm$?$:
