the picture didn't shows up very good, it's a 100ohm and a 50mH in series and parrell with a 50ohm and a 20*10^-6F in series

Homework Statement What is the current supplied by the emf when the frequency is very large and very small? ------------------------- | | | ------------------------ | | | |...

I got the answer from masteringphysics.com 1.67*10^-13 T. Now what is the magnetic field strength 7cm from the axis?

I think you need to change the unites for the increase rate to C/s. anyone knows how?
